Struct BufferRef 

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

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

Implementations

impl<'a> BufferRef<'a>

pub fn len(&self) -> usize

Returns the buffer’s capacity.

pub fn is_empty(&self) -> bool

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

Returns a slice of the buffer’s contents.

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

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

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

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

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

Returns the range in the underlying BufferSource that this BufferRef 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 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_ptr_slice(&self) -> PtrByteSlice<'a>

Returns a read-only pointer slice over the buffer.
