Traits
-
is_basic_outcome<T>An integral constant type true for
basic_outcome<T, EC, EP, NoValuePolicy>types. -
is_basic_result<T>An integral constant type true for
basic_result<T, E, NoValuePolicy>types. -
is_error_code_available<T>True if an error code can be constructed from a
T. -
is_error_type<E>A customisable integral constant type true for
Etypes which are to receive error throwing no-value policies. -
is_error_type_enum<E, Enum>A customisable integral constant type true for
Etypes constructible fromEnumtypes which are to receive error throwing no-value policies. -
is_exception_ptr_available<T>True if an exception ptr can be constructed from a
T. -
is_failure_type<T>An integral constant boolean variable true for
failure_type<EC, E = void>types. -
is_move_bitcopying<T>(>= Outcome v2.2.0) A customisable integral constant type true for
Ttypes which are move bitcopying safe. -
is_success_type<T>An integral constant boolean variable true for
success_type<T>types. -
type_can_be_used_in_basic_result<R>A constexpr boolean true for types permissible in
basic_result<T, E, NoValuePolicy>.
