Trait Implementations

impl<'a> ByteWriter for DataGenOutput<'a>

fn write_byte(&mut self, b: u8)

Writes a single byte.

fn write_bytes(&mut self, v: &[u8])

Writes a number of bytes.

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. RawEncoders are recommended but not required to call this method with an appropriate estimate. By default this method does nothing.
