Struct AsyncStdChild

pub struct AsyncStdChild { /* private fields */ }

Async-std specific RuntimeChild implementation.

Trait Implementations

impl RuntimeChild for AsyncStdChild

type Runtime = AsyncStdGlobalRuntime

An async runtime.

type Stdin<'a> = AsyncStdStdin<'a> where Self: 'a

Represents a stdin implementation specific to runtime.

type Stdout<'a> = AsyncStdStdout<'a> where Self: 'a

Represents a stdout implementation specific to runtime.

type Stderr<'a> = AsyncStdStderr<'a> where Self: 'a

Represents a stderr implementation specific to runtime.

fn stdin(&mut self) -> Option<Self::Stdin<'_>>

Returns child’s stdin.

fn stdout(&mut self) -> Option<Self::Stdout<'_>>

Returns child’s stdout.

fn stderr(&mut self) -> Option<Self::Stderr<'_>>

Returns child’s stderr.

fn id(&self) -> u32

Returns the OS-assigned process identifier associated with this child.

fn kill(&mut self) -> Result<()>

Forces the child process to exit. If the child has already exited, Ok(()) is returned.

fn output(self) -> impl Future<Output = Result<Output>> + Send

Simultaneously waits for the child to exit and collect all remaining output on the stdout/stderr handles, returning an Output instance.

fn status(&mut self) -> impl Future<Output = Result<ExitStatus>> + Send

Waits for the child to exit completely, returning the status that it exited with. This function will continue to have the same return value after it has been called at least once.

fn try_status(&mut self) -> Result<Option<ExitStatus>>

Attempts to collect the exit status of the child if it has already exited.
