Required Methods

source

fn write_sized<F>(&mut self, len: usize, write: F) where
F: for<'_> FnOnce(&mut [u8]),

Calls write with a slice of len bytes at the current write position

source

fn write_slice(&mut self, slice: &[u8])

Copies the slice into the buffer

source

fn write_repeated(&mut self, count: usize, value: u8)

Repeatedly write a byte value for a given count

let mut buffer = vec![255; 1024];
let mut encoder = EncoderBuffer::new(&mut buffer);
encoder.encode(&1u8);
encoder.write_repeated(4, 0);
assert_eq!(&buffer[0..6], &[1, 0, 0, 0, 0, 255]);
