Trait PtyChild 

pub trait PtyChild: Send + Sync {
    // Required methods
    fn pid(&self) -> u32;
    fn is_running(&self) -> bool;
    fn wait(
        &mut self,
    ) -> Pin<Box<dyn Future<Output = Result<ExitStatus>> + Send + '_>>;
    fn try_wait(&mut self) -> Result<Option<ExitStatus>>;
    fn signal(&self, signal: PtySignal) -> Result<()>;
    fn kill(&mut self) -> Result<()>;
}

Handle for a child process spawned in a PTY.

This trait provides methods for monitoring and controlling the child process. It’s separate from PtyMaster to allow independent lifetime management of the PTY and the process.

Required Methods

fn pid(&self) -> u32

Get the process ID of the child.

fn is_running(&self) -> bool

Check if the child process is still running.

fn wait( &mut self, ) -> Pin<Box<dyn Future<Output = Result<ExitStatus>> + Send + '_>>

Wait for the child process to exit.

Returns the exit status when the process terminates.

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

Try to get the exit status without blocking.

Returns None if the process is still running.

fn signal(&self, signal: PtySignal) -> Result<()>

Send a signal to the child process.

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

Kill the child process.

This sends SIGKILL on Unix or calls TerminateProcess on Windows.

Dyn Compatibility

This trait is dyn compatible.

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