std::expected<T,E>::operator bool, std::expected<T,E>::has_value

< cpp‎ | utility‎ | expected
constexpr explicit operator bool() const noexcept;
 (since C++23)
constexpr bool has_value() const noexcept;
 (since C++23)

Checks whether *this contains an expected value.

Parameters

(none)

Return value

true if *this contains an expected value, false if *this contains an unexpected value.

Notes

A std::expected object is never empty. If has_value() returns true, operator* can be used to access the contained value; otherwise, error() can be used.
