Struct ErrorEncoder

pub struct ErrorEncoder;

An encoder that always returns error.

Implementations

impl ErrorEncoder

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

Trait Implementations

impl Clone for ErrorEncoder

fn clone(&self) -> ErrorEncoder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl RawEncoder for ErrorEncoder

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

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

fn raw_feed( &mut self, input: &str, _output: &mut dyn ByteWriter, ) -> (usize, Option<CodecError>)

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

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

Finishes the encoder, pushes the an encoded byte sequence at the end of the given output, and returns optional error information (None means success). remaining value of the error information, if any, is always an empty string.

fn is_ascii_compatible(&self) -> bool

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