Struct Bytes

pub struct Bytes<'a> { /* private fields */ }

A slice wrapper that implements BytesRead.

Implementations

impl<'a> Bytes<'a>

pub fn new(position: usize, inner: &'a [u8]) -> Self

You should probably use:

let bytes: Bytes = slice.into();
// or
let bytes = Bytes::from(slice);

pub fn inner(&self) -> &'a [u8]

Returns the inner slice with the original reference.
