Optional value wrapper for error indication without exceptions

Provides a way to indicate errors in return-by-value functions without using slow exceptions. Functionally almost identical to std::optional<T>, but with API naming adapted to byeol project conventions.

For normal operation, pass the value as T& to the constructor. For error situations, pass a tmedium class created as nullptr.

Remarks: Why use tmedium? See tmedium for details on why this intermediate type is used.; Common naming conventions The functions has(), get(), rel(), and set() follow naming conventions used throughout the entire project.

Usage

Example of using tmay for error handling:

tmay<std::string> loadConfig(const std::string& path) {
    if(!fileExists(path))
        return tmay<std::string>(); // Return empty for error
 
    std::string content = readFile(path);
    return tmay<std::string>(content); // Return value for success
}
 
auto config = loadConfig("config.txt");
if(config.has()) {
    std::string& value = config.get();
    processConfig(value);
}

참고: Use tstr<T> or tweak<T> for return-by-reference cases

멤버 함수 문서화

◆ get()

template<typename T >

T * by::tmay< T >::get ( )

Gets the contained value.

경고: Calling get() on an empty tmay instance results in undefined behavior. It is recommended to check with has() before calling this.

반환값: Pointer to the contained value.

◆ set()

template<typename T >

virtual void by::tmay< T >::set ( const T & arg )

virtual

by::tres< T, R >에서 재구현되었습니다.
