Struct heph_rt::bytes::LimitedBytes

pub struct LimitedBytes<B> { /* private fields */ }

Wrapper to limit the number of bytes B can use.

See Bytes::limit and BytesVectored::limit.

Implementations

impl<B> LimitedBytes<B>

pub fn into_inner(self) -> B

Returns the underlying buffer.

Trait Implementations

impl<B> Bytes for LimitedBytes<B>where
    B: Bytes,

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

Returns itself as a slice of bytes that may or may not be initialised.

fn spare_capacity(&self) -> usize

Returns the length of the buffer as returned by as_bytes.

fn has_spare_capacity(&self) -> bool

Returns true if the buffer has spare capacity.

unsafe fn update_length(&mut self, n: usize)

Update the length of the byte slice, marking n bytes as initialised.

fn limit(self, limit: usize) -> LimitedBytes<Self>where
    Self: Sized,

Wrap the buffer in LimitedBytes, which limits the amount of bytes used to limit.

impl<B> BytesVectored for LimitedBytes<B>where
    B: BytesVectored,

type Bufs<'b>
where
    Self: 'b = <B as BytesVectored>::Bufs<'b>

Type used as slice of buffers, usually this is an array.

fn as_bufs<'b>(&'b mut self) -> Self::Bufs<'b>

Returns itself as a slice of MaybeUninitSlice.

fn spare_capacity(&self) -> usize

Returns the total length of the buffers as returned by as_bufs.

fn has_spare_capacity(&self) -> bool

Returns true if (one of) the buffers has spare capacity.

unsafe fn update_lengths(&mut self, n: usize)

Update the length of the buffers in the slice.

fn limit(self, limit: usize) -> LimitedBytes<Self>where
    Self: Sized,

Wrap the buffer in LimitedBytes, which limits the amount of bytes used to limit.

impl<B: Debug> Debug for LimitedBytes<B>

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

Formats the value using the given formatter.
