Crate rightkit_child_process 

OwnedCommand::inherit_handles_only restricts inheritance to caller handles/fds plus stdio; Windows requires windows_spawn_config for opaque Command settings.

Modules

reveal

Reveal a file or folder in the system file manager, or open it with its default handler, through OwnedCommand, and only inside caller-supplied roots.

Structs

Ack

Handed to the watched party; calling Ack::done proves it is alive.

AdoptedIdentity

A pid together with the start time and executable path that make it a name for exactly one process. See the module documentation.

AdoptedProcess

BudgetLabels

Names and scale of the load behind an IdleObservation, for IdleObservation::result_lines.

ConsecutiveFailures

Cap on restarts granted in a row without the replacement ever reporting ready.

Cooldown

Minimum spacing between expensive actions (HeardRight samples stacks at most once a minute). Pure; the caller supplies now.

Generation

HealthPolicy

HealthTracker

IdleObservation

What a process did over a quiet window: the idle figures a runtime budget names.

JobAssignmentFailure

Every failed assignment in a best-effort Windows spawn is retained.

OwnedChild

OwnedCommand

ProcessHandle

An independent exit reader. On Unix it shares the owner’s cached reap state; on Windows it owns a duplicated process handle, never a borrowed handle value. Keeping this reader alive does not keep an owned process tree alive.

ProcessUsage

One snapshot of the current process’s resource usage.

RestartPermit

RestartPolicy

RestartTracker

StallConfig

StallWatchdog

A running watchdog. Dropping it stops and joins the thread.

StartToken

When a process started, in the host’s own unit (macOS: seconds and microseconds; Linux: clock ticks since boot and 0; Windows: 100 ns ticks since 1601 and 0). Comparable only on the host that produced it.

StderrTail

A background drain of one stderr stream. Keeps the most recent lines whose total size is at most max_bytes; older lines fall off the front. A single line that alone exceeds the budget is cut to its last bytes, so snapshot never returns more than max_bytes bytes.

SweepReport

The result of sweep, as pids.

TerminationOptions

UnixChild

A spawned Unix child. The same API as Windows’ WindowsChild: public stdio fields, id, try_wait, wait and kill. It does not expose the std Child, because a std reap the crate cannot see would make later group signals unsafe (see the module documentation).

UsageRates

Rates between two snapshots. Each rate is None when either snapshot lacks the counter.

Enums

AdoptedSignal

How hard to stop a process. Windows has one way to stop a process, so both are the same there.

HealthOutcome

HealthProbe

IdentityCheck

What a pid names now, compared with a remembered identity.

JobAssignmentMode

ReapOutcome

RestartMode

RestartOutcome

SignalResult

The outcome of AdoptedIdentity::signal.

StallEvent

UnixContainment

WaitOutcome

Constants

DEFAULT_DROP_REAP_TIMEOUT

How long Drop waits for a killed leader to be reaped before handing the reap to a background thread.

DEFAULT_ENV_ALLOWLIST

Functions

observe_idle

Sleeps duration on the calling thread and reports the process’s usage over it. Run it after the load has stopped; it is for benches and tests, so a host reads process_usage instead.

process_usage

Resource usage of the current process, computed now.

sweep

Stops every process in targets that is still the process it was remembered as: a graceful signal to each, up to grace for them to leave, then a forced signal to those still present. A target whose pid names a different process is refused, never signalled. Targets are signalled in the order given; pass leaves first (the reverse of AdoptedIdentity::descendants).

sweep_descendants

sweep of root’s current descendants, leaves first. The root itself is left alone.
