constexpr text_encoding( std::text_encoding::id i ) noexcept; |
(3) | (since C++26) |
Constructs a new text encoding object.
1) Default constructor. Constructs an object with MIBenum value std::text_encoding::id::unknown and empty character encoding name.
If enc names a registered character encoding other than
NATS-DANO
or NATS-DANO-ADD
, then the constructed object will have the corresponding MIBenum value, otherwise it will have MIBenum std::text_encoding::id::other. Behavior is undefined if enc.size() > std::text_encoding::max_name_length || enc.contains('\0').
If i is std::text_encoding::id::other or std::text_encoding::id::unknown, then the constructed object will have empty character encoding name, otherwise it will have one of the corresponding names.
Behavior is undefined if i is not a named enumerator of
std::text_encoding::id
.Parameters
enc | - | character encoding name |
i | - | MIBenum value |
