Struct LinuxSupervisor 

pub struct LinuxSupervisor { /* private fields */ }

Real PID-1 backend. Uses libc fork/execve/waitpid/kill. Safe to compile on macOS (same libc surface); running meaningfully requires being PID 1 in a Linux kernel.

Implementations

impl LinuxSupervisor

pub fn new() -> Self

Trait Implementations

impl Default for LinuxSupervisor

fn default() -> Self

Returns the “default value” for a type.

impl Supervisor for LinuxSupervisor

Available on Unix only.

fn spawn(&mut self, svc: &Service) -> Result<Pid>

Spawn a service; return its PID.

fn terminate(&mut self, pid: Pid) -> Result<()>

Deliver SIGTERM to a PID. For graceful termination.

fn kill(&mut self, pid: Pid) -> Result<()>

Deliver SIGKILL. For the last resort.

fn reap_one(&mut self) -> Result<Option<(Pid, i32)>>

Block until any child exits, or return None immediately if no children have exited. Returns (pid, exit_status) when available.

fn children(&self) -> Vec<(Pid, String)>

Live children tracked by this supervisor.
