Struct BufferRef

pub struct BufferRef { /* private fields */ }

An immutable reference to a buffer. Can be used for shared zero copy views into a single buffer.

Implementations

impl BufferRef

pub fn new(inner: Arc<Buffer>, start: usize, len: usize) -> Self

Creates a shared reference to given buffer.

Panics

Panics if start + len overflows or if start + len is greater than inner.len().

pub fn slice(&self, start: usize, len: usize) -> Self

Slices into this ref.

Panics

Panics if start + len overflows or if start + len is greater than self.len(). Or if self.start + start overflows.

pub fn len(&self) -> usize

Length of the reference

pub fn is_empty(&self) -> bool

Returns if length of buffer is zero

pub fn inner_len(&self) -> usize

Length of the underlying buffer

pub fn start(&self) -> usize

Start index of this reference relative to the inner buffer.

pub fn as_ptr(&self) -> *const u8

Return a pointer to the underlying memory at offset

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

Get a slice

Trait Implementations

impl Clone for BufferRef

fn clone(&self) -> BufferRef

Returns a copy of the value.

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

Performs copy-assignment from source.
