Struct compio_buf::OwnedIter

pub struct OwnedIter<I: OwnedIterator>(/* private fields */);

An owned buffer iterator for vectored buffers. See IoVectoredBuf::owned_iter.

Implementations

impl<I: OwnedIterator> OwnedIter<I>

pub fn new(inner: I) -> Self

Create OwnedIter from inner impls.

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

Get the next buffer. Will return Err with the inner buffer if it reaches the end.

Trait Implementations

impl<I: Debug + OwnedIterator> Debug for OwnedIter<I>

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

Formats the value using the given formatter.

impl<I: OwnedIterator> IntoInner for OwnedIter<I>

type Inner = <I as IntoInner>::Inner

The inner type.

fn into_inner(self) -> Self::Inner

Get the inner buffer.

impl<I: OwnedIterator + 'static> IoBuf for OwnedIter<I>

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<I: OwnedIteratorMut + 'static> IoBufMut for OwnedIter<I>

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<I: OwnedIteratorMut + 'static> SetBufInit for OwnedIter<I>

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

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