Enum thread_priority::unix::NormalThreadSchedulePolicy

pub enum NormalThreadSchedulePolicy {
    Other,
}

Normal (non-realtime) schedule policies For these schedule policies, niceness is used.

Variants

Other

The standard round-robin time-sharing policy, also sometimes referred to as “Normal”.

SCHED_OTHER can be used at only static priority 0 (i.e., threads under real-time policies always have priority over SCHED_OTHER processes). SCHED_OTHER is the standard Linux time-sharing scheduler that is intended for all threads that do not require the special real-time mechanisms.

The thread to run is chosen from the static priority 0 list based on a dynamic priority that is determined only inside this list. The dynamic priority is based on the nice value (see below) and is increased for each time quantum the thread is ready to run, but denied to run by the scheduler.

This ensures fair progress among all SCHED_OTHER threads.

In the Linux kernel source code, the SCHED_OTHER policy is actually named SCHED_NORMAL.

Trait Implementations

impl Clone for NormalThreadSchedulePolicy

fn clone(&self) -> NormalThreadSchedulePolicy

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NormalThreadSchedulePolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for NormalThreadSchedulePolicy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NormalThreadSchedulePolicy

fn cmp(&self, other: &NormalThreadSchedulePolicy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NormalThreadSchedulePolicy

fn eq(&self, other: &NormalThreadSchedulePolicy) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NormalThreadSchedulePolicy

fn partial_cmp(&self, other: &NormalThreadSchedulePolicy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
