Enum ThreadingPolicy 

#[repr(C)]
pub enum ThreadingPolicy {
    Single,
    Fixed(usize),
    Adaptive,
}

Declares thread policy usage

Variants

Single

Will use only one current thread

Fixed(usize)

Spawn provided threads count, will not work for wasm - fallback to Single

Adaptive

Computes adaptive thread count between 1…available parallelism for given image bounds, will not work for wasm - fallback to Single

Implementations

impl ThreadingPolicy

pub fn thread_count(&self, for_size: ImageSize) -> usize

Available on non-WebAssembly only.

Returns the number of threads to use for the given image dimensions under the selected policy variant.

impl ThreadingPolicy

pub fn get_pool(&self, for_size: ImageSize) -> Option<ThreadPool>

Available on non-WebAssembly only.

Trait Implementations

impl Clone for ThreadingPolicy

fn clone(&self) -> ThreadingPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadingPolicy

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

Formats the value using the given formatter.

impl Default for ThreadingPolicy

fn default() -> ThreadingPolicy

Returns the “default value” for a type.

impl Ord for ThreadingPolicy

fn cmp(&self, other: &ThreadingPolicy) -> 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,

Restrict a value to a certain interval.

impl PartialEq for ThreadingPolicy

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for ThreadingPolicy

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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