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 AsyncRead for Mock

pub fn poll_read(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut ReadBuf<'_>
) -> Poll<Result<()>>

Attempts to read from the AsyncRead into buf.

impl AsyncWrite for Mock

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

Attempt to write bytes from buf into the object.

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

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

pub 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.

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

Like poll_write, except that it writes from a slice of buffers.

pub fn is_write_vectored(&self) -> bool

Determines if this writer has an efficient poll_write_vectored implementation.

impl Debug for Mock

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

Formats the value using the given formatter.

impl Drop for Mock

Ensures that Mock isn't dropped with data "inside".

pub fn drop(&mut self)

Executes the destructor for this type.
