Struct BufferRef

Source 
pub struct BufferRef<'a> { /* private fields */ }
Expand description

BufferRef is an unowned, read-only view over a Buffer.

Implementations§

Source§

impl<'a> BufferRef<'a>

Source

pub fn len(&self) -> usize

Returns the buffer’s capacity.

Source

pub fn is_empty(&self) -> bool

Source

pub fn as_slice(&self) -> &[u8] ⓘ

Returns a slice of the buffer’s contents.

Source

pub fn subslice<R: SliceRange>(&self, range: R) -> BufferRef<'_>

Slices and consumes this reference. See Buffer::subslice.

Source

pub fn split_at(&self, mid: usize) -> (BufferRef<'_>, BufferRef<'_>)

Splits at |mid| (included in the right child), yielding two BufferRefs.

Source

pub fn range(&self) -> Range<usize>

Returns the range in the underlying BufferSource that this BufferRef covers. TODO(jfsulliv): Currently unused in host code. Remove when there is a real Device impl.
