Struct tokio::process::ChildStderr

pub struct ChildStderr { /* private fields */ }

The standard error stream for spawned children.

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

Implementations

impl ChildStderr

pub fn from_std(inner: ChildStderr) -> Result<Self>

Creates an asynchronous ChildStderr from a synchronous one.

Errors

This method may fail if an error is encountered when setting the pipe to non-blocking mode, or when registering the pipe with the runtime’s IO driver.

    buf: &mut ReadBuf<'_>
) -> Poll<Result<()>>
