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<'_>

Returns a read-only view of the buffer.

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

Consumes this reference and returns a read-only view.

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.

pub fn copy_to_slice(&self, dest: &mut [u8])

Copies the contents of this buffer into dest.

Panics

Panics if dest.len() != self.len().

pub fn copy_from_slice(&mut self, src: &[u8])

Copies the contents of src into this buffer.

Panics

Panics if src.len() != self.len().

pub fn copy_from_buffer(&mut self, src: BufferRef<'_>)

Copies the contents of src buffer into this buffer.

Panics

Panics if src.len() != self.len().

pub fn fill(&mut self, val: u8)

Fills the buffer with val.

pub fn to_vec(&self) -> Vec<u8>

Returns the buffer’s contents as a Vec.

pub fn append_to(&self, vec: &mut Vec<u8>)

Appends the buffer’s contents to vec.

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

Returns a raw pointer to the buffer’s contents.

pub fn as_mut_ptr(&mut self) -> *mut u8

Returns a mutable raw pointer to the buffer’s contents.

pub fn as_ptr_slice(&self) -> PtrByteSlice<'_>

Returns a read-only pointer slice over the buffer.

pub fn as_mut_ptr_slice(&mut self) -> MutPtrByteSlice<'_>

Returns a mutable pointer slice over the buffer.

pub fn into_mut_ptr_slice(self) -> MutPtrByteSlice<'a>

Consumes this reference and returns a mutable pointer slice.
