Struct ProcessRunner 

pub struct ProcessRunner;

Synchronous bounded child-process runner.

On Unix, each child is placed in a new process group. Capture pipes are nonblocking and are closed after a bounded drain grace, so even a descendant that escapes the group cannot hold ProcessRunner::run open indefinitely. Platforms without this implementation fail before spawning with ProcessRunError::UnsupportedPlatformGuarantee.

Implementations

impl ProcessRunner

pub fn run(spec: &ProcessSpec) -> Result<ProcessOutcome, ProcessRunError>

Run the specified child, concurrently drain stdout/stderr, enforce the deadline, and return only after the child has been reaped.

pub fn run_cancellable( spec: &ProcessSpec, cancellation: &ProcessCancellation, ) -> Result<ProcessOutcome, ProcessRunError>

Run with an explicit cooperative cancellation token.
