/**
 * @brief The namespace providing primitive types.
 * @details
 * When I writing with Rust, I notice that most pf primitive types has explicit and exact size, and their names are short and clear.
 * Hoeever, in C++, most primitive types are variable based on system, due to the legacy of C era.
 * All primitive types with explicit size are only can be fetched in a specific header file,
 * and, their names are too long because they can not be registered as reserved keywords or names
 * due to the name conflict with so much code written in past years.
 * However, STL can't do this but I can do this.
 * I invent this namespace providing primitive types, such as integers, floating-point numbers, and strings, 
 * in Rust style, their names areshort and clear.
