Struct fire_http_representation::bytes_stream::MoreBytes

pub struct MoreBytes { /* fields omitted */ }

A structure that holds multiple Bytes.

It makes it possible to implement io::Read over it to make for example deserialization a bit more memory efficient.

Implementations

impl MoreBytes

pub fn is_empty(&self) -> bool

Returns true if there are no bytes left.

pub fn len(&self) -> usize

Returns how many bytes are still remaining.

Note

Here not the struct Bytes are counted but the actual byte amount.

pub fn next_bytes(&mut self) -> Option<Bytes>

Returning the next Bytes removing it from MoreBytes.

pub fn to_vec(&self) -> Vec<u8>

Combines all Bytes into one big Vec.

Note

Avoid this if possible, since it’s not really Efficient.

pub async fn copy_to_async_write<W>(&self, writer: &mut W) -> Result<()> where
    W: AsyncWrite + Unpin, 

Writes all bytes to an AsyncWrite implementor.

Trait Implementations

impl BytesStream for MoreBytes

fn poll_bytes(
    self: Pin<&mut Self>,
    _: &mut Context<'_>
) -> Poll<Result<Option<Bytes>>>

This will always return Poll::Ready(Ok(_)).

impl Read for MoreBytes

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

This won’t never return an error.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8, Global>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.
