result.h File Reference

Detailed Description

result<T, E> type alias for fl::expected (Rust-style naming)

This file provides a Rust-style naming alias for the C++23-style expected type. The underlying implementation is in fl/stl/expected.h.

Example usage:

result<int> divide(int a, int b) {
    if (b == 0) {
        return result<int>::failure(ResultError::INVALID_ARGUMENT, "Division by zero");
    }
    return result<int>::success(a / b);
}
 
auto r = divide(10, 2);
if (r.ok()) {
    int value = r.value();
}
