Struct encoding::codec::utf_16::UTF16Encoding
[−]
[src]
pub struct UTF16Encoding<E> { // some fields omitted }
UTF-16 (UCS Transformation Format, 16-bit).
This is a Unicode encoding where one codepoint may use 2 (up to U+FFFF) or 4 bytes (up to U+10FFFF) depending on its value. It uses a "surrogate" mechanism to encode non-BMP codepoints, which are represented as a pair of lower surrogate and upper surrogate characters. In this effect, surrogate characters (U+D800..DFFF) cannot appear alone and cannot be included in a valid Unicode string.
Specialization
This type is specialized with endianness type E
,
which should be either Little
(little endian) or Big
(big endian).

[src]
fn clone(&self) -> UTF16Encoding<E>
Returns a copy of the value. Read more

impl<E: Endian> Encoding for UTF16Encoding<E>
[src]
fn name(&self) -> &'static str
Returns the canonical name of given encoding. This name is guaranteed to be unique across built-in encodings, but it is not normative and would be at most arbitrary. Read more
fn whatwg_name(&self) -> Option<&'static str>
Returns a name of given encoding defined in the WHATWG Encoding standard, if any. This name often differs from name
due to the compatibility reason. Read more
fn raw_encoder(&self) -> Box<RawEncoder>
Creates a new encoder.
fn raw_decoder(&self) -> Box<RawDecoder>
Creates a new decoder.
fn encode(&self, input: &str, trap: EncoderTrap) -> Result<Vec<u8>, Cow<'static, str>>
An easy-to-use interface to RawEncoder
. On the encoder error trap
is called, which may return a replacement sequence to continue processing, or a failure to return the error. Read more
fn encode_to(&self, input: &str, trap: EncoderTrap, ret: &mut ByteWriter) -> Result<(), Cow<'static, str>>
Encode into a ByteWriter
.
fn decode(&self, input: &[u8], trap: DecoderTrap) -> Result<String, Cow<'static, str>>
An easy-to-use interface to RawDecoder
. On the decoder error trap
is called, which may return a replacement string to continue processing, or a failure to return the error. Read more
fn decode_to(&self, input: &[u8], trap: DecoderTrap, ret: &mut StringWriter) -> Result<(), Cow<'static, str>>
Decode into a StringWriter
. Read more
