Expand description
String writer used by decoders. In most cases this will be an owned string.
Required Methods§
Sourcefn write_char(&mut self, c: char)
fn write_char(&mut self, c: char)
Writes a single character.
Provided Methods§
Sourcefn writer_hint(&mut self, _expectedlen: usize)
fn writer_hint(&mut self, _expectedlen: usize)
Hints an expected lower bound on the length (in bytes) of the output
until the next call to writer_hint
,
so that the writer can reserve the memory for writing.
RawDecoder
s are recommended but not required to call this method
with an appropriate estimate.
By default this method does nothing.
