Struct IoBuffer

pub struct IoBuffer {
    pointer: *mut u8,
    size: usize,
    layout: Option<Layout>,
}

Owned memory buffer.

Fields

pointer: *mut u8

Raw pointer to the start of the buffer.

size: usize

Size in bytes.

layout: Option<Layout>

Allocation layout. None only for null buffers.

Implementations

impl IoBuffer

pub fn new(size: usize, alignment: usize) -> Result<Self>

Create a new owned buffer, containing uninitialized data.

Do note that the returned buffer contains uninitialized data, which however is perfectly fine for an I/O buffer.

pub fn new_with_layout(layout: Layout) -> Result<Self>

Create a new owned buffer, containing uninitialized data, with the given layout.

pub fn len(&self) -> usize

Length in bytes.

pub fn is_empty(&self) -> bool

Whether this is a null buffer (length is 0).

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

Generate an immutable reference.

pub fn as_ref_range(&self, range: Range<usize>) -> IoBufferRef<'_>

Generate an immutable reference to a sub-range.

pub fn as_mut(&mut self) -> IoBufferMut<'_>

Generate a mutable reference.

pub fn as_mut_range(&mut self, range: Range<usize>) -> IoBufferMut<'_>

Generate a mutable reference to a sub-range.
