Struct MutableBufferRef

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

MutableBufferRef is an unowned, read-write view of a Buffer.

Implementations

impl<'a> MutableBufferRef<'a>

pub fn len(&self) -> usize

Returns the buffer’s capacity.

pub fn is_empty(&self) -> bool

pub fn as_ref(&self) -> BufferRef<'_>

pub fn into_ref(self) -> BufferRef<'a>

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

Returns a slice of the buffer’s contents.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Returns a mutable slice of the buffer’s contents.

pub fn reborrow(&mut self) -> MutableBufferRef<'_>

Reborrows this reference with a lesser lifetime. This mirrors the usual borrowing semantics (i.e. the borrow ends when the new reference goes out of scope), and exists so that a MutableBufferRef can be subsliced without consuming it.

For example: let mut buf: MutableBufferRef<’_> = …; { let sub = buf.reborrow().subslice_mut(a..b); }

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

Slices this reference. See Buffer::subslice.

pub fn subslice_mut<R: SliceRange>(self, range: R) -> MutableBufferRef<'a>

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

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

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

pub fn split_at_mut( self, mid: usize, ) -> (MutableBufferRef<'a>, MutableBufferRef<'a>)

Consumes the reference and splits it at |mid| (included in the right child), yielding two MutableBufferRefs.

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

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

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

Formats the value using the given formatter.
