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<dyn RawEncoder>

Creates a new encoder.

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

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 dyn 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 dyn 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.
