NAME¶

std::expected::operatorbool,std::expected::has_value - std::expected::operatorbool,std::expected::has_value

Synopsis¶

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.
