Struct VectoredBufIter 

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

An owned iterator over a vectored buffer.

Normally one would use IoVectoredBuf::owned_iter to create this iterator.

Implementations

impl<T> VectoredBufIter<T>

pub fn next(self) -> Result<VectoredBufIter<T>, T>

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

Trait Implementations

impl<T> IntoInner for VectoredBufIter<T>

type Inner = T

The inner type.

fn into_inner(self) -> <VectoredBufIter<T> as IntoInner>::Inner

Get the inner buffer.

impl<T> IoBuf for VectoredBufIter<T>

where T: IoVectoredBuf,

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

Get the slice of initialized bytes.

fn buf_len(&self) -> usize

Length of initialized bytes in the buffer.

fn buf_ptr(&self) -> *const u8

Raw pointer to the buffer.

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

where Self: Sized,

Returns a view of the buffer with the specified range.

impl<T> IoBufMut for VectoredBufIter<T>

where T: IoVectoredBufMut,

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

Get the full mutable slice of the buffer, including both initialized and uninitialized bytes.

fn buf_capacity(&mut self) -> usize

Total capacity of the buffer, including both initialized and uninitialized bytes.

fn buf_mut_ptr(&mut self) -> *mut MaybeUninit<u8>

Get the raw mutable pointer to the buffer.

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

Get the mutable slice of initialized bytes. The content is the same as IoBuf::as_init, but mutable.

fn reserve(&mut self, len: usize) -> Result<(), ReserveError>

Reserve additional capacity for the buffer.

fn reserve_exact(&mut self, len: usize) -> Result<(), ReserveExactError>

Reserve exactly len additional capacity for the buffer.

fn uninit(self) -> Uninit<Self>

where Self: Sized,

Returns an Uninit, which is a Slice that only exposes uninitialized bytes.

fn is_filled(&mut self) -> bool

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

impl<T> SetLen for VectoredBufIter<T>

where T: IoVectoredBuf + SetLen,

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

Set the buffer length.

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

where Self: IoBuf,

Set the buffer length to len. If len is less than the current length, this operation is a no-op.

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

where Self: IoVectoredBuf,

Set the vector buffer’s total length to len. If len is less than the current total length, this operation is a no-op.

fn clear(&mut self)

where Self: IoBuf,

Clear the buffer, setting its length to 0 without touching its content or capacity.
