Struct encoding::codec::error::ErrorDecoder

pub struct ErrorDecoder;

A decoder that always returns error.

Implementations

impl ErrorDecoder

pub fn new() -> Box<dyn RawDecoder>

Trait Implementations

impl Clone for ErrorDecoder

fn clone(&self) -> ErrorDecoder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl RawDecoder for ErrorDecoder

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

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

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

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).

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

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

fn is_ascii_compatible(&self) -> bool

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.
