Struct compio_buf::IndexedIter

pub struct IndexedIter<T> { /* private fields */ }

An owned iterator over an indexable container.

Implementations

impl<T: Indexable> IndexedIter<T>

pub fn new(bufs: T) -> Result<Self, T>

Create a new IndexedIter from an indexable container. If the container is empty, return the buffer back in Err(T).

Trait Implementations

impl<T> IntoInner for IndexedIter<T>

type Inner = T

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<T> IoBuf for IndexedIter<T>

where T: Indexable + 'static, T::Output: IoBuf,

fn as_buf_ptr(&self) -> *const u8

Returns a raw pointer to the vector’s buffer.

fn buf_len(&self) -> usize

Number of initialized bytes.

fn buf_capacity(&self) -> usize

Total size of the buffer, including uninitialized memory, if any.

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

Get the initialized part of the buffer.

unsafe fn as_io_slice(&self) -> IoSlice

Create an IoSlice of this buffer.

fn slice(self, range: impl RangeBounds<usize>) -> Slice<Self>

where Self: Sized,

Returns a view of the buffer with the specified range.

fn filled(&self) -> bool

Indicate whether the buffer has been filled (uninit portion is empty)

impl<T> IoBufMut for IndexedIter<T>

where T: IndexableMut + 'static, T::Output: IoBufMut,

fn as_buf_mut_ptr(&mut self) -> *mut u8

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

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

Get the uninitialized part of the buffer.

unsafe fn as_io_slice_mut(&mut self) -> IoSliceMut

Create an IoSliceMut of the uninitialized part of the buffer.

impl<T: Indexable> OwnedIterator for IndexedIter<T>

fn next(self) -> Result<Self, Self::Inner>

Get the next iterator.

impl<T> SetBufInit for IndexedIter<T>

where T: IndexableMut, T::Output: IoBufMut,

unsafe fn set_buf_init(&mut self, len: usize)

Set the buffer length. If len is less than the current length, nothing should happen.
