◆ expectedCast() [1/2]

template<typename RelatedType , typename Type , typename Error >

constexpr auto expectedCast ( const expected< Type, Error > & source ) -> expected<RelatedType, Error>

This function casts the expected to an expected with a related type and the same error type, using an explicit cast to convert the value. This allows casting even if the target type is not implicitly, but explicitly constructible to the source type.
