Struct ThreadCount 

pub struct ThreadCount(/* private fields */);

A non-zero thread count.

Implementations

impl ThreadCount

pub fn new(value: usize) -> Result<ThreadCount, ThreadCountError>

Creates a thread count from a non-zero value.

Errors

Returns ThreadCountError::Zero when value is zero.

pub const fn get(self) -> usize

Returns the count value.

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<(), Error>

Formats the value using the given formatter.

impl Display for ThreadCount

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

Formats the value using the given formatter.

impl From<NonZero<usize>> for ThreadCount

fn from(value: NonZero<usize>) -> ThreadCount

Converts to this type from the input type.

impl Hash for ThreadCount

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

where __H: Hasher,

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 ThreadCount

fn cmp(&self, other: &ThreadCount) -> 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 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 PartialOrd for ThreadCount

fn partial_cmp(&self, other: &ThreadCount) -> 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.

impl TryFrom<usize> for ThreadCount

type Error = ThreadCountError

The type returned in the event of a conversion error.

fn try_from( value: usize, ) -> Result<ThreadCount, <ThreadCount as TryFrom<usize>>::Error>

Performs the conversion.
