[−][src]Trait encoding::types::RawDecoder

pub trait RawDecoder: 'static {
    fn from_self(&self) -> Box<dyn RawDecoder>;

    fn raw_feed(
        &mut self, 
        input: &[u8], 
        output: &mut dyn StringWriter
    ) -> (usize, Option<CodecError>);

    fn raw_finish(
        &mut self, 
        output: &mut dyn StringWriter
    ) -> Option<CodecError>;

    fn is_ascii_compatible(&self) -> bool { ... }
}

Decoder converting a byte sequence into a Unicode string. This is a lower level interface, and normally Encoding::decode should be used instead.

Required Methods

Creates a fresh RawDecoder instance which parameters are same as self.

Feeds given portion of byte sequence to the encoder, pushes the a decoded string at the end of the given output, and returns an offset to the first unprocessed byte (that can be zero when the first such byte appeared in the prior calls to raw_feed) and optional error information (None means success).

Finishes the decoder, pushes the a decoded string at the end of the given output, and returns optional error information (None means success).

Provided Methods

Returns true if this encoding is compatible to ASCII, i.e. bytes 00 through 7F always map to U+0000 through U+007F and nothing else.
