Module process 

process.rs — OS layer: spawn, capped IO drain, process-tree kill.

Structs

RawResult

Result of a successful (possibly timed-out) execution.

Functions

drain_with_cap

Drain a reader into Bytes, stopping storage (but continuing to drain) once cap is reached. Sets truncated=true if the stream exceeded the cap.

kill_tree

Kill the whole process group (Unix). Best-effort on Windows (post-v1: job object). M-5: guard against pid 0/None (would signal the caller’s own group if the child already exited and id() returned None).

spawn

Spawn the child in its own process group (Unix) with given env/cwd/args. kill_on_drop(true) is a belt-and-suspenders guard so an accidentally-dropped Child never leaks a process (C-1 defense in depth).
