Struct Threads 

pub struct Threads(pub NonZero<usize>);

How many threads a run’s parallel work may use; one is the serial run.

Tuple Fields

0: NonZero<usize>

Implementations

impl Threads

pub const ONE: Threads

One thread: the serial run.

pub fn new(n: usize) -> Option<Threads>

n threads; None for zero.

pub fn get(self) -> usize

The thread count.

Trait Implementations

impl Clone for Threads

fn clone(&self) -> Threads

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Threads

impl Debug for Threads

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

Formats the value using the given formatter.

impl Default for Threads

fn default() -> Threads

One: the serial run.

impl Eq for Threads

impl PartialEq for Threads

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

Equality operator ==.

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

Inequality operator !=.

impl Resource for Threads

const NAME: &'static str = "core.threads"

const VERSION: u32 = 1

fn to_json(&self) -> Result<Option<Value>, JsonError>

As Component::to_json.

fn verify(&self, _w: &World) -> Result<(), String>

The resource’s own invariants in w; as Component::verify, run by the pass manager’s verifier.

fn references(&self, _out: &mut Vec<Entity>)

The entities this resource refers to, appended to out. A resource holding entity references must declare every one of them and implement Resource::retain_references.

fn retain_references(&mut self, _keep: &dyn Fn(Entity) -> bool)

Forget every reference to an entity keep refuses (set it to “none”). The world calls it whenever entities leave it (World::despawn, World::retain, World::move_components) and on the copy a World::subset or World::split_off part gets, so a resource never refers to an entity its world lacks.

impl RunSetting for Threads

fn text(&self) -> String

The value as a run report states it (threads 16).
