Enum ThreadCount 

pub enum ThreadCount {
    AvailableParallelism,
    Count(NonZeroUsize),
}

Available on crate features rayon or default-thread-pool only.

Number of threads to spawn in a thread pool.

Variants

AvailableParallelism

Spawn the number of threads returned by std::thread::available_parallelism().

Count(NonZeroUsize)

Spawn the given number of threads.

Implementations

impl ThreadCount

pub fn count(self) -> NonZeroUsize

Resolves the number of threads to spawn.

Trait Implementations

impl Clone for ThreadCount

fn clone(&self) -> ThreadCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadCount

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

Formats the value using the given formatter.

impl PartialEq for ThreadCount

fn eq(&self, other: &ThreadCount) -> 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 TryFrom<usize> for ThreadCount

type Error = <NonZero<usize> as TryFrom<usize>>::Error

The type returned in the event of a conversion error.

fn try_from(thread_count: usize) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ThreadCount

impl Eq for ThreadCount

impl StructuralPartialEq for ThreadCount
