Required Methods

fn bytes(&self) -> &[u8]

The whole buffer as a slice.

fn len(&self) -> usize

The length of the data in the buffer.

fn truncate(&mut self, new_len: usize) -> Result<(), BufferError>

Truncates the buffer to the given length.

fn write_array_at<const BYTES: usize>( &mut self, offset: usize, data: [u8; BYTES] ) -> Result<(), BufferError>

Writes the given data at the given offset.

fn write_bytes(&mut self, data: &[u8]) -> Result<(), BufferError>

Writes the given data at the end of the buffer.

fn write_array<const BYTES: usize>( &mut self, data: [u8; BYTES] ) -> Result<(), BufferError>

Writes the given data at the end of the buffer.

fn read_bytes_at( &self, offset: usize, length: usize ) -> Result<&[u8], BufferError>

Reads a given number of bytes at the given offset.

fn read_bytes_at_mut( &mut self, offset: usize, length: usize ) -> Result<&mut [u8], BufferError>

Reads a given number of bytes at the given offset.
