Struct Supervisor 

pub struct Supervisor { /* private fields */ }

Minimal PID-file supervision for long_running actions: start detached in a fresh process group with output to a log file, record the PID, stop by signaling the group. No daemon, no restart policy.

Implementations

impl Supervisor

pub fn new(state_dir: Utf8PathBuf) -> Self

state_dir is per instance: .newgit/state/<slug>/.

pub fn running_pid(&self, resource: &str) -> Option<u32>

pub fn start( &self, resource: &str, command: &str, cwd: &Utf8Path, env: &[(String, String)], log_path: &Utf8Path, ) -> Result<u32>

pub fn stop(&self, resource: &str, signal: &str) -> Result<StopOutcome>

Signal the process group and wait up to ~5s for it to exit.

pub fn prune_dead_pids(&self, dry_run: bool) -> Result<Vec<Utf8PathBuf>>

Remove PID files whose process group is gone — a process that died on its own, or outlived a reboot. Returns what was removed, or what would be under dry_run.

Trait Implementations

impl Clone for Supervisor

fn clone(&self) -> Supervisor

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Supervisor

fn fmt(&self, f: &mut Formatter<'_>) -> Result
