Struct tokio::process::ChildStdout

pub struct ChildStdout { /* fields omitted */ }

The standard output stream for spawned children.

This type implements the AsyncRead trait to read data from the stdout handle of a child process asynchronously.

Trait Implementations

impl AsRawFd for ChildStdout

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl AsyncRead for ChildStdout

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

Attempts 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: BufMut>(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut B
) -> Poll<Result<usize>> where
    Self: Sized, 

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

impl Debug for ChildStdout

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

Formats the value using the given formatter.
