Module unit 

Varlink proxy for the io.systemd.Unit interface on PID 1’s socket. Adapted from the interface definition in systemd’s src/core/varlink-unit.c. The List method exists from v258, but the per-type context sections monitord reads land later: src/core/varlink-service.c and src/core/varlink-timer.c first appear in v261, so that is the real minimum for anything here.

Only the fields monitord maps onto its own stats types are declared; serde drops the rest, which is most of a ~7KB per-unit reply.

Note that systemd omits fields sitting at their default rather than sending a zero, so almost everything here is optional and the caller supplies the default (see varlink_units, where those defaults have to match what the D-Bus properties return for the same unit).

Structs

CGroupRuntime

cgroup accounting for a unit. Fields appear only when the matching accounting option is enabled for the unit.

ExecContext

Execution configuration shared by every unit type that runs processes.

ListOutput

Output parameters for the List method.

ProcessId

A process reference, carrying the pid plus fields that disambiguate reuse.

ServiceContext

Service-specific configuration.

ServiceRuntime

Service-specific runtime state.

TimerContext

Timer-specific configuration.

TimerRuntime

Timer-specific runtime state.

Timestamp

A systemd timestamp, carrying both clocks.

UnitContext

Configuration of a unit.

UnitRuntime

Runtime state of a unit.

Enums

UnitError

Errors that can occur in the io.systemd.Unit interface.

Traits

Unit

Proxy trait for calling methods on the io.systemd.Unit interface.

UnitChain

Extension trait for adding proxy calls to any chain.
