 - For output parameters, use `u32::from` for the conversion.
+
+## Enum Types
+
+Enum types in Rust are quite diverse, so we need to adopt different strategies for different variants.
+
+### Plain Enums
+
+The plain enum type is the simplest kind, as shown below:
+
+```rust
+enum Plain {
+    Entry1,
+    Entry2,
+}
+```
+
+For a plain enum type, we first need to choose an underlying type for it, just like the `enum class` in C++. The chosen underlying type needs to be specified on this enum type via the `repr` attribute. Then, when passing across the FFI boundary, we use this underlying type. Specifically:
+
+- Use the chosen underlying type as the parameter type in the function signature.
+- For input parameters, convert from the chosen underlying type to our enum, and verify that it is a valid enum field value.
+- For output parameters, convert the enum to the chosen underlying type, and then pass it out.
+
+These conversion and validation methods for input and output parameters can be written by hand, but we recommend using an existing package to accomplish this more conveniently. Choose the library suitable for your FFI project according to the following situations:
+
+- Use the `num_enum` package (lightweight; use it when your project does not use `strum`).
+- Use the `strum` and `strum_macros` packages (heavier; use them when your project already uses `strum`).
+
+#### Using `num_enum`
+
+An example of using the `num_enum` package to conveniently perform conversion and validation is as follows:
+
+```rust
+#[derive(Debug, PartialEq, Eq, IntoPrimitive, TryFromPrimitive)]
+#[repr(u8)]
+enum Number {
+    Zero,
+    One,
+}
+
+fn foobar() {
+    // Convert the enum to the chosen underlying type.
+    let zero: u8 = Number::Zero.into();
+    assert_eq!(zero, 0u8);
+
+    // Convert from the chosen underlying type to the enum (success case).
+    let zero = Number::try_from(0u8);
+    assert_eq!(zero, Ok(Number::Zero));
+    // Convert from the chosen underlying type to the enum (failure case).
+    let three = Number::try_from(3u8);
+    assert!(three.is_err());
+}
+```
+
+#### Using `strum` and `strum_macros`
+
+An example of using the `strum` and `strum_macros` packages to conveniently perform conversion and validation is as follows:
+
+```rust
+#[derive(Debug, PartialEq, FromRepr)]
+#[repr(u8)]
+enum Number {
+    One = 1,
+    Three = 3,
+}
+
+fn foobar() {
+    // Convert the enum to the chosen underlying type.
+    let one: u8 = Number::One as u8;
+    assert_eq!(one, 1u8);
+
+    // Convert from the chosen underlying type to the enum (success case).
+    assert_eq!(Some(Number::One), Number::from_repr(1));
+    // Convert from the chosen underlying type to the enum (failure case).
+    assert_eq!(None, Number::from_repr(0));
+}
+```
+
+#### Enum Types from Other Crates
+
+In most cases, the enum type comes from another crate (because we develop with the two-project structure). In this case, Rust does not allow you to attach attribute tags to a type from outside your own crate. The solution is to create a wrapper type in your own crate, decorate it with attributes, and implement the bidirectional `From` traits. As shown below:
+
+```rust
+use another_crate::Example as InternExample;
+
+#[repr(u8)]
+enum Example {
+    // Entries omitted...
+}
+
+impl From<Example> for InternExample {
+    // Implementation omitted...
+}
+
+impl From<InternExample> for Example {
+    // Implementation omitted...
+}
+```
+
+### Flag Enums
+
+The best practice for flag-style enums in Rust is `bitflags`, as shown below. We assume that you are using `bitflags` to implement all flag-style enums in your project.
+
+```rust
+bitflags! {
+    pub struct Flags: u32 {
+        const A = 0b00000001;
+        const B = 0b00000010;
+        const C = 0b00000100;
+    }
+}
+```
+
+Similarly, we also need to choose an underlying type for it. The difference is that when using `bitflags` we have already specified this underlying type, so there is no need to specify it additionally. When passing across the FFI boundary, follow the same requirements as the plain enum types.
+
+We also need to establish the conversion and validation connection between this enum type and the chosen underlying type. Fortunately, `bitflags` already provides these functions for us, for example the automatically generated `from_bits` method and the `bits` method from the `Flags` trait. For example:
+
+```rust
+bitflags! {
+    pub struct Flags: u32 {
+        const A = 0b00000001;
+        const B = 0b00000010;
+        const C = 0b00000100;
+    }
+}
+
+fn foobar() {
+    // Convert the enum to the chosen underlying type.
+    let flags = Flags::A | Flags::B;
+    let bits: u32 = flags.bits();
+    assert_eq!(bits, 0b00000011u32);
+
+    // Convert from the chosen underlying type to the enum (success case).
+    let success = Flags::from_bits(0b00000101u32);
+    assert_eq!(success, Some(Flags::A | Flags::C));
+    // Convert from the chosen underlying type to the enum (failure case).
+    let failure = Flags::from_bits(0b00001000u32);
+    assert_eq!(failure, None);
+}
+```
+
+### Payload Enums
+
+The payload enum is the most complex kind of enum type, for example:
+
+```rust
+enum Message {
+    Quit,
+    Move { x: i32, y: i32 },
+    Write(String),
+    ChangeColor(u8, u8, u8),
+}
+```
+
+We require that payload enums be converted into opaque structs for access. Put the payload enum into a struct, use a plain enum type to distinguish the different payload entries, and provide different methods to access the different entries. For example:
+
+```rust
+use some_crate::Message as InternMessage;
+
+struct Message {
+    inner: InternMessage,
+}
+
+enum MessageKind {
+    // Entries omitted...
+}
+
+impl Message {
+    pub fn get_kind(&self) -> MessageKind {
+        // Contents omitted...
+    }
+
+    pub fn get_write_entry(&self) -> &str {
+        // Contents omitted...
+    }
+
+    // The access functions for the following entries are omitted...
+}
+```

+# Library Architecture
+
+The functions exported in a library can be roughly divided into two categories: auxiliary functions and functional functions.
+
+## Auxiliary Functions
+
+Auxiliary functions do not perform the main functionality of the library. They help the functional functions work properly.
+
+### Startup/Shutdown Functions
+
+Startup/shutdown functions are a category of auxiliary functions, as shown in the following example:
+
+```rust
+#[unsafe(no_mangle)]
+pub extern "C" fn WFStartup() -> CError {
+    // Function body omitted...
+}
+
+#[unsafe(no_mangle)]
+pub extern "C" fn WFShutdown() -> () {
+    // Function body omitted...
+}
+```
+
+Here `WF` is the `<PREFIX>`, indicating that these are startup/shutdown functions exclusive to this library. Usually the word `startup` is used as the `<FUNC>` of the startup function and the word `shutdown` is used as the `<FUNC>` of the shutdown function. Other names may be chosen according to the preference of the library author.
+
+These functions usually have no input or output parameters, but this is not mandatory. The library author may add parameters as needed.
+
+Among these functions, the return value of the startup function is `CError`, and the return value of the shutdown function is `()` (that is, `void` in C/C++). The return value types of these two cannot be changed. The reason for setting the return values this way is: when the startup function runs, it may return some errors to explicitly inform the user that initialization failed, so its return value is `CError`. As for the shutdown function, in order to more closely match the semantics of Rust's `Drop` and C++ destructors, its return value is `()`.
+
+When implementing these functions on the Rust side and using them in C/C++, you need to guarantee:
+
+- Any call to a functional function must be after the call to the startup function and before the call to the shutdown function. Otherwise these functional functions must return an error code to indicate this error.
+- The startup/shutdown functions can be called repeatedly, but the startup and shutdown functions must appear in pairs. This is similar to Win32 COM's `CoInitialize` and `CoUninitialize`.
+
+You may use the `library_lifecycle` module provided by the crate to simplify the writing of the startup/shutdown functions.
+
+Startup/shutdown functions are an optional kind of auxiliary function. If your library will not fail when initializing DLL-level resources, there is no need to add startup/shutdown functions. You can directly use Rust's lazy loading mechanism (for example `LazyLock`) so that the resources are loaded when the DLL is loaded and released when the DLL is released.
+
+### Error Information Functions
+
+Error information functions are used to return the error information of the last call. Here is an example:
+
+```rust
+#[unsafe(no_mangle)]
+pub extern "C" fn WFGetErrorMessage() -> CStrPtr {
+    // Function body omitted...
+}
+```
+
+Here `WF` is the `<PREFIX>`, indicating that this is the error information function exclusive to this library. Usually the phrase "get last error" or "get error message" is used as the `<FUNC>` of the error information function. Other names may be chosen according to the preference of the library author.
+
+The return value of the error information function is not `CError` but `CStrPtr`. `CStrPtr` is a type in the `cstr_ffi` module provided by the crate. This is among the few functions in the whole library whose return value is not `CError`.
+
+When implementing the error information function, you should guarantee that its return value is based on the last call on the current thread rather than the last call on the process.
+
+You may use the `last_error` module provided by the crate to simplify the writing of the error information function. Furthermore, by properly using `cffi_wrapper!`, you can simplify the writing of the error information function to the greatest extent, without even touching the `last_error` module.
+
+## Functional Functions
+
+Functional functions are the main part of the exported functions. They are responsible for actually performing the main functionality of the library.
+
+Functional functions can be ordinary functions or opaque struct functions, depending on the needs of the function itself.

 # Miscellaneous Stuff
+
+## Two-Project Workspace Structure
+
+When writing FFI, we require you to develop with two projects using the Rust workspace mechanism. For example:
+
+- An ordinary Rust library project named `foobar`. In this project you write your library logic in a pure Rust way.
+- An FFI-specific library project named `foobar-ffi` (the name does not have to be exactly this; you may choose any name that fits your need). This project references `foobar` within the workspace, writes the relevant code according to this design, wraps `foobar` into a form suitable for FFI export, and finally exports it in FFI form.
+
+## Panic Policy
+
+In the FFI project, we enforce that every panic causes the process to exit immediately, just like executing `std::abort` in C++. So you need to specify the following in the Cargo.toml of the FFI project, so that this feature is enabled only in the production environment (that is, the release mode):
+
+```toml
+[profile.release]
+panic = "abort"
+```
+
+The reason for enabling this feature only in the release mode is that in the debug mode you may need to perform operations such as stack tracing to debug the project, and enabling this feature would make such operations impossible.
+
+You may think this operation would cause the user's process to crash frequently. But a well-designed library should be able to catch all recoverable errors and try not to trigger any unrecoverable errors. This operation forces developers to design a well-functioning library and eliminate potential errors during the development stage.
+
+## Artifact Type
+
+The build artifact of the FFI project should meet the requirements of the C language FFI. So you need to specify the following in the Cargo.toml of the FFI project to set the produced artifact type:
+
+```toml
+[lib]
+crate-type = ["cdylib"]
+```
+
+## Module Organization
+
+In the FFI project, do not try to pile everything into `lib.rs`. You need to make reasonable use of the Rust module mechanism. For example:
+
+- When combining multiple Rust types to create an opaque struct dedicated to FFI, you can write it in a module named like `wrapper` (the name does not have to be exactly this; you may choose any name that fits your need).
+- When re-wrapping Rust types, you can write it in a module named like `ffi_types` (the name does not have to be exactly this; you may choose any name that fits your need).
+
+`lib.rs` should contain only the following:
+
+- User-defined error types, `Result` types, `CError` constants and so on.
+- The constants and types to export, including those defined directly with `pub type` and `pub const`, and those defined indirectly with `pub use` from other modules.
+- All the FFI functions to export.
+
+The re-wrapped contents can be written in a separate module `wrapper.rs`. `lib.rs` only contains the error definitions, the types to export, the constants and the functions.
+
+## Dependency Specification
+
+When adding `sarasacw-omrf` to the dependencies of the FFI project, we require specifying it as a git repository, supplemented with a tag and the `version` field, to ensure the version is correct. As shown below:
+
+```toml
+sarasacw-omrf = { version="1.0.0", git = "https://github.com/SarasasChipWorkshop/sarasacw-omrf.git", tag = "omrf/1.0.0" }
