Struct Bytes

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

A cursor over a slice of bytes.

Implementations

impl<'a> Bytes<'a>

pub const fn from_slice(bytes: &'a [u8]) -> Self

Returns a new cursor over a slice of bytes.

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

Consumes the Bytes and returns the underlying data.

pub const fn position(&self) -> usize

Returns the current position of the Bytes.

pub fn advance(&mut self, size: usize) -> Result<()>

Advances the position in the bytes.

pub fn align(&mut self, align: usize) -> Result<()>

Aligns the bytes to a particular word.

Panics

If the align size is a not one of the following powers of two: 1, 2, 4, 8, or 16.

pub fn read<T: FromBytes>(&mut self) -> Result<T, <T as FromBytes>::Error>

Allows types implementing FromBytes to be easily read from these bytes.

Examples

let mut bytes = Bytes::from_slice(&[0x78, 0x56, 0x34, 0x12]);
let value: u32 = bytes.read().unwrap();
assert_eq!(value, 0x12345678);

Trait Implementations

impl<'a> Clone for Bytes<'a>

fn clone(&self) -> Bytes<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Bytes<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for Bytes<'a>

fn from(bytes: &'a [u8]) -> Self

Converts to this type from the input type.
