Struct tokio_test::io::Mock

pub struct Mock { /* fields omitted */ }

An I/O object that follows a predefined script.

This value is created by Builder and implements AsyncRead + AsyncWrite. It follows the scenario described by the builder and panics otherwise.

Trait Implementations

impl Debug for Mock

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

Formats the value using the given formatter.

impl AsyncRead for Mock

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

Attempt to read from the AsyncRead into buf.

unsafe fn prepare_uninitialized_buffer(
    &self,
    buf: &mut [MaybeUninit<u8>]
) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

fn poll_read_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: BufMut, 

Pull some bytes from this source into the specified BufMut, returning how many bytes were read.

impl AsyncWrite for Mock

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_write_buf<B: Buf>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize>>

Write a Buf into this value, returning how many bytes were written.

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

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.
