    inner: B,
    len: usize,
    cap: usize,
}

Fields§

Implementations§

Source§

impl<B> Buffer<B>
where B: AsMut<[u8]> + AsRef<[u8]>,

Source

pub fn new(b: B) -> Self

Constructs a new, empty Buffer.

Source

pub fn len(&self) -> usize

Returns the number of elements in the buffer.

Source

pub fn resize(&mut self, new_size: usize)

Resizes the buffer in-place so that len is equal to new_size.

Source

pub fn extend_from_slice(&mut self, bytes: &[u8])

Appends all elements in a slice to the buffer.

Source

pub fn advance(&mut self, cnt: usize)

Shortens the buffer, dropping the first cnt bytes and keeping the rest.

Source

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.
