Trait ByteWriter

Source
pub trait ByteWriter {
    // Required methods
    fn write_byte(&mut self, b: u8);
    fn write_bytes(&mut self, v: &[u8]);

    // Provided method
    fn writer_hint(&mut self, _expectedlen: usize) { ... }
}
Expand description

Byte writer used by encoders. In most cases this will be an owned vector of u8.

Required Methods§

Source

fn write_byte(&mut self, b: u8)

Writes a single byte.

Source

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

Writes a number of bytes.

Provided Methods§

Source

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.
