Struct HZEncoding

pub struct HZEncoding;

HZ. (RFC 1843)

This is a simplified Chinese encoding based on GB 2312. It bears a resemblance to ISO 2022 encodings in such that the printable escape sequences ~{ and ~} are used to delimit a sequence of 7-bit-safe GB 2312 sequences. For the comparison, they are equivalent to ISO-2022-CN escape sequences ESC $ ) A and ESC ( B. Additional escape sequences ~~ (for a literal ~) and ~\n (ignored) are also supported.

Trait Implementations

impl Clone for HZEncoding

fn clone(&self) -> HZEncoding

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Encoding for HZEncoding

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

Creates a new encoder.

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

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.
