Struct UTF16Encoding

Source
pub struct UTF16Encoding<E> { /* private fields */ }
Expand description

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).

impl<E: Endian> Encoding for UTF16Encoding<E>

Source§

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.
Source§

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.
Source§

fn raw_encoder(&self) -> Box<dyn RawEncoder>

Creates a new encoder.
Source§

fn raw_decoder(&self) -> Box<dyn RawDecoder>

Creates a new decoder.
Source§

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.
Source§

fn encode_to( &self, input: &str, trap: EncoderTrap, ret: &mut dyn ByteWriter, ) -> Result<(), Cow<'static, str>>

Encode into a ByteWriter.
Source§

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.
Source§

fn decode_to( &self, input: &[u8], trap: DecoderTrap, ret: &mut dyn StringWriter, ) -> Result<(), Cow<'static, str>>

Decode into a StringWriter. Read more
