Struct tokio::process::ChildStdout

pub struct ChildStdout { /* private fields */ }

Available on crate feature process only.

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.

Implementations

impl ChildStdout

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

Creates an asynchronous ChildStdout 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.
