Trait ProcessControl 

pub trait ProcessControl: Send {
    // Required methods
    fn pid(&self) -> Option<u32>;
    fn kill_tree(&self);
    fn wait(&mut self) -> BoxFuture<'_, Result<ExitStatus>>;
    fn close_output(&mut self);
}

Control half of a running process.

Required Methods

fn pid(&self) -> Option<u32>

OS process id, when known.

fn kill_tree(&self)

Kills the process and all its descendants (killProcessTree: killpg(SIGKILL) on Unix, taskkill /F /T on Windows). Never fails; a dead process is ignored.

fn wait(&mut self) -> BoxFuture<'_, Result<ExitStatus>>

Waits for the process to exit. Cancel-safe.

fn close_output(&mut self)

Stops reading output (pipes inherited by detached descendants may never close).

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
