Struct oci_spec::runtime::Scheduler

source ·
pub struct Scheduler { /* private fields */ }
Expand description

Scheduler represents the scheduling attributes for a process. It is based on the Linux sched_setattr(2) syscall.

Implementations§

source§

impl Scheduler

source

pub fn policy(&self) -> &LinuxSchedulerPolicy

Policy represents the scheduling policy (e.g., SCHED_FIFO, SCHED_RR, SCHED_OTHER).

source

pub fn nice(&self) -> &Option<i32>

Nice is the nice value for the process, which affects its priority.

source

pub fn priority(&self) -> &Option<i32>

Priority represents the static priority of the process.

source

pub fn flags(&self) -> &Option<Vec<LinuxSchedulerFlag>>

Flags is an array of scheduling flags.

source

pub fn runtime(&self) -> &Option<u64>

Runtime is the amount of time in nanoseconds during which the process is allowed to run in a given period.

source

pub fn deadline(&self) -> &Option<u64>

Deadline is the absolute deadline for the process to complete its execution.

source

pub fn period(&self) -> &Option<u64>

Period is the length of the period in nanoseconds used for determining the process runtime.

source§

impl Scheduler

source

pub fn set_policy(&mut self, val: LinuxSchedulerPolicy) -> &mut Self

Policy represents the scheduling policy (e.g., SCHED_FIFO, SCHED_RR, SCHED_OTHER).

source

pub fn set_nice(&mut self, val: Option<i32>) -> &mut Self

Nice is the nice value for the process, which affects its priority.

source

pub fn set_priority(&mut self, val: Option<i32>) -> &mut Self

Priority represents the static priority of the process.

source

pub fn set_flags(&mut self, val: Option<Vec<LinuxSchedulerFlag>>) -> &mut Self

Flags is an array of scheduling flags.

source

pub fn set_runtime(&mut self, val: Option<u64>) -> &mut Self

Runtime is the amount of time in nanoseconds during which the process is allowed to run in a given period.

source

pub fn set_deadline(&mut self, val: Option<u64>) -> &mut Self

Deadline is the absolute deadline for the process to complete its execution.

source

pub fn set_period(&mut self, val: Option<u64>) -> &mut Self

Period is the length of the period in nanoseconds used for determining the process runtime.
