Character encoding.

Required Methods

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.

fn raw_encoder(&self) -> Box<RawEncoder + 'static>

Creates a new encoder.

fn raw_decoder(&self) -> Box<RawDecoder + 'static>

Creates a new decoder.

Provided Methods

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.

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.

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.

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

Decode into a StringWriter.

This does not handle partial characters at the beginning or end of input! Use RawDecoder for incremental decoding.
