Trait encoding::types::RawEncoder
[−]
[src]
pub trait RawEncoder: 'static { fn from_self(&self) -> Box<RawEncoder>; fn raw_feed(&mut self, input: &str, output: &mut ByteWriter) -> (usize, Option<CodecError>); fn raw_finish(&mut self, output: &mut ByteWriter) -> Option<CodecError>; fn is_ascii_compatible(&self) -> bool { ... } }
Encoder converting a Unicode string into a byte sequence.
This is a lower level interface, and normally Encoding::encode
should be used instead.
Required Methods
fn from_self(&self) -> Box<RawEncoder>
Creates a fresh RawEncoder
instance which parameters are same as self
.
fn raw_feed(&mut self, input: &str, output: &mut 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 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.
Provided Methods
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.
