Required Methods§
sourcefn write_sized<F>(&mut self, len: usize, write: F)
fn write_sized<F>(&mut self, len: usize, write: F)
Calls write
with a slice of len
bytes at the current write position
sourcefn write_slice(&mut self, slice: &[u8])
fn write_slice(&mut self, slice: &[u8])
Copies the slice into the buffer
sourcefn write_zerocopy<T, F>(&mut self, write: F)
fn write_zerocopy<T, F>(&mut self, write: F)
Writes a zerocopy value to the buffer
sourcefn write_repeated(&mut self, count: usize, value: u8)
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]);
Provided Methods§
sourcefn encode<T>(&mut self, value: &T)where
T: EncoderValue,
fn encode<T>(&mut self, value: &T)where
T: EncoderValue,
Encode the given EncoderValue
into the buffer
sourcefn encode_with_len_prefix<Len, T>(&mut self, value: &T)
fn encode_with_len_prefix<Len, T>(&mut self, value: &T)
Encode the given EncoderValue
into the buffer with a prefix of Len
sourcefn remaining_capacity(&self) -> usize
fn remaining_capacity(&self) -> usize
Returns the number of available bytes in the buffer
