Expand description

A subprocess.

Implementations§

Source§

impl<Stream: AsyncStream, T: Object> Child<Stream, T>

Source

pub fn get_kill_handle(&self) -> KillHandle

Get a handle for process termination.

Source

pub fn id(&self) -> pid_t

Get ID of the process.

Source

pub async fn join(self) -> Result<T>

Wait for the process to finish and obtain the value it returns.

An error is returned if the process panics or is terminated. An error is also delivered if it exits via std::process::exit or alike instead of returning a value, unless the return type is (). In that case, Ok(()) is returned.
