Struct encoding::codec::tradchinese::BigFive2003Encoding

pub struct BigFive2003Encoding;

Big5-2003 with common extensions. (XXX with asymmetric HKSCS-2008 support)

This is a traditional Chinese encoding spanning the region [81-FE] [40-7E A1-FE]. Originally a proprietary encoding by the consortium of five companies (hence the name), the Republic of China government standardized Big5-2003 in an appendix of CNS 11643 so that CNS 11643 plane 1 and plane 2 have an almost identical set of characters as Big5 (but with a different mapping). The Hong Kong government has an official extension to Big5 named Hong Kong Supplementary Character Set (HKSCS).

This particular implementation of Big5 includes the widespread ETEN and HKSCS extensions, but excludes less common extensions such as Big5+, Big-5E and Unicode-at-on.

Trait Implementations

impl Encoding for BigFive2003Encoding

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.

impl Clone for BigFive2003Encoding

fn clone(&self) -> BigFive2003Encoding

Returns a copy of the value.

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

Performs copy-assignment from source.
