Detailed Description

template<typename TError>
class etl::expected< void, TError >

Specialisation for void value type.

Member Function Documentation

ETL_NODISCARD ETL_CONSTEXPR14 value_type * etl::expected< void, TError >::begin ( )

inline

Returns a pointer to the value if has_value(), otherwise returns nullptr. Allows expected to be used as a range of 0 or 1 elements.

template<typename TError>

const error_type & etl::expected< void, TError >::error ( ) const

inline

Returns the error Undefined behaviour if an error has not been set.
