Enum thread_priority::ThreadPriority

pub enum ThreadPriority {
    Min,
    Specific(u32),
    Max,
}

Thread priority enumeration.

Variants

Min

Holds a value representing the minimum possible priority.

Specific(u32)

Holds a specific priority value. Should be in [0; 100] range, a percentage value. The u32 value is reserved for different OS’es support.

Max

Holds a value representing the maximum possible priority. Should be used with caution, it solely depends on the target os where the program is going to be running on, how it will behave. On some systems, the whole system may become frozen if not used properly.

Implementations

impl ThreadPriority

pub fn to_posix(self, policy: ThreadSchedulePolicy) -> Result<c_int, Error>

POSIX value can not be known without knowing the scheduling policy https://linux.die.net/man/2/sched_get_priority_max

pub fn from_posix(params: ScheduleParams) -> ThreadPriority

Gets priority value from POSIX value. In order to interpret it correctly, you should also take scheduling policy into account.

impl ThreadPriority

pub fn set_for_current(self) -> Result<(), Error>

Sets current thread’s priority to this value.

Trait Implementations

impl Clone for ThreadPriority

fn clone(&self) -> ThreadPriority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadPriority

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

Formats the value using the given formatter.

impl Ord for ThreadPriority

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<ThreadPriority> for ThreadPriority

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

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

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

This method tests for !=.

impl PartialOrd<ThreadPriority> for ThreadPriority

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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