Struct BufRef

pub struct BufRef(pub usize, pub usize);

A BufRef is a reference to a buffer of bytes. It removes the need for self-referential data structures. It is safe to use as long as the underlying buffer does not get mutated.

Panics

This will panic if an index is out of bounds.

Tuple Fields

0: usize

1: usize

Implementations

impl BufRef

pub fn get<'a>(&self, buf: &'a [u8]) -> &'a [u8]

Return a sub-slice of buf.

pub fn get_bytes(&self, buf: &Bytes) -> Bytes

Return a slice of buf. This operation is O(1) and increases the reference count of buf.

pub fn len(&self) -> usize

Return the size of the slice reference.

pub fn is_empty(&self) -> bool

Return true if the length is zero.

impl BufRef

pub fn new(start: usize, len: usize) -> Self

Initialize a BufRef that can reference a slice beginning at index start and has a length of len.

Trait Implementations

impl Clone for BufRef

fn clone(&self) -> BufRef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BufRef

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

Formats the value using the given formatter.

impl PartialEq for BufRef

fn eq(&self, other: &BufRef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
