Struct CpuScheduling

pub struct CpuScheduling { /* private fields */ }

The CPU scheduling for running a transient service on the system service manager. See CPUSchedulingPolicy=, CPUSchedulingPriority=, and CPUSchedulingResetOnFork= in systemd.exec(5) and sched_setscheduler(2) for details.

Implementations

impl CpuScheduling

pub fn batch() -> Self

For “batch” style execution of processes, SCHED_BATCH.

pub fn idle() -> Self

For running very low priority background jobs, SCHED_IDLE.

pub fn fifo(p: NonZeroU8) -> Self

A first-in, first-out real-time policy, SCHED_FIFO, with specified priority. The priority must be in [1, 99].

This would be unavailable if the feature systemd_252 is disabled because it was broken by systemd #20320. Use Self::fifo_default_priority instead.

pub fn fifo_default_priority() -> Self

Like Self::fifo but with default priority.

pub fn round_robin(p: NonZeroU8) -> Self

A round-robin real-time policy, SCHED_RR, with specified priority. The priority must be in [1, 99].

This would be unavailable if the feature systemd_252 is disabled because it was broken by systemd #20320. Use Self::round_robin_default_priority instead.

pub fn round_robin_default_priority() -> Self

Like Self::round_robin but with default priority.

pub fn reset_on_fork(self) -> Self

Make the children created by fork(2) do not inherit privileged scheduling policies.

Trait Implementations

impl Default for CpuScheduling

fn default() -> Self

The default CPU scheduling policy, SCHED_OTHER.
