Struct encoding::codec::japanese::Windows31JEncoding

pub struct Windows31JEncoding;

Windows code page 932, i.e. Shift_JIS with IBM/NEC extensions.

This is a Japanese encoding for JIS X 0208 compatible to the original assignments of JIS X 0201 ([21-7E A1-DF]). The 94 by 94 region of JIS X 0208 is sliced, or rather "shifted" into the odd half (odd row number) and even half (even row number), and merged into the 188 by 47 region mapped to [81-9F E0-EF] [40-7E 80-FC]. The remaining area, [80 A0 F0-FF] [40-7E 80-FC], has been subjected to numerous extensions incompatible to each other. This particular implementation uses IBM/NEC extensions which assigns more characters to [F0-FC 80-FC] and also to the Private Use Area (PUA). It requires some cares to handle since the second byte of JIS X 0208 can have its MSB unset.

Trait Implementations

impl Clone for Windows31JEncoding

fn clone(&self) -> Windows31JEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Windows31JEncoding

impl Encoding for Windows31JEncoding

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<RawEncoder>

Creates a new encoder.

fn raw_decoder(&self) -> Box<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 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.
