template<typename T>
concept kcenon::common::concepts::OptionalLike =  requires(const T t) {
    { t.has_value() } -> std::convertible_to<bool>;
    { t.is_some() } -> std::convertible_to<bool>;
    { t.is_none() } -> std::convertible_to<bool>;
}

Detailed Description

A type that represents an optional value (present or absent).

Types satisfying this concept provide has_value(), is_some(), and is_none() methods for querying the presence of a value.

Example usage:

template<OptionalLike O>
void process_if_present(const O& opt) {
    if (opt.has_value()) {
        // Use opt.value()
    }
}
