Struct CopyBuffer 

pub struct CopyBuffer { /* private fields */ }

A fixed-capacity byte buffer supporting copy-in and copy-out operations.

Implementations

impl CopyBuffer

pub fn new(capacity: usize) -> Self

pub fn capacity(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn remaining(&self) -> usize

pub fn copy_in(&mut self, src: &[u8]) -> usize

Copy bytes in. Returns number of bytes actually written.

pub fn copy_out(&mut self, n: usize) -> Vec<u8>

Copy out up to n bytes from the front. Returns the slice.

pub fn peek(&self, n: usize) -> &[u8]

Peek at up to n bytes without consuming them.

pub fn clear(&mut self)

pub fn as_slice(&self) -> &[u8]

pub fn is_full(&self) -> bool

True if capacity is reached.

pub fn fill(&mut self, byte: u8)

Fill with a repeated byte value.

pub fn set_byte(&mut self, pos: usize, byte: u8) -> bool

Overwrite byte at position; returns false if out of range.

pub fn get_byte(&self, pos: usize) -> Option<u8>

Trait Implementations

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CopyBuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result
