Struct futures_mockstream::MockStream

pub struct MockStream { /* fields omitted */ }

A Mock Stream with implements AsyncRead, AsyncWrite, and Stream from the futures crate.

Examples

let mock_stream = MockStream::from(&b"mock stream buffer"[..]);

Methods

impl MockStream

pub fn from(buf: &[u8]) -> Self

Creates a MockStream from a reference of array.

Arguments

A reference of array of u8.

Examples

let mockstream = MockStream::from("hello".as_bytes());

Trait Implementations

impl AsRef<[u8]> for MockStream

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

Performs the conversion.

impl AsyncRead for MockStream

fn poll_read(
    self: Pin<&mut Self>,
    _cx: &mut Context,
    buf: &mut [u8]
) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context,
    bufs: &mut [IoSliceMut]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl AsyncWrite for MockStream

fn poll_write(
    self: Pin<&mut Self>,
    _cx: &mut Context,
    buf: &[u8]
) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, _cx: &mut Context) -> Poll<Result<()>>

Attempt to close the object.

fn poll_write_vectored(
    self: Pin<&mut Self>,
    cx: &mut Context,
    bufs: &[IoSlice]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.

impl Debug for MockStream

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

Formats the value using the given formatter.

impl Default for MockStream

fn default() -> MockStream

Returns the "default value" for a type.

impl Stream for MockStream

type Item = Result<Vec<u8>, Error>

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
