Enum Threading 

pub enum Threading {
    Single,
    Funneled,
    Serialized,
    Multiple,
}

The level of thread support, matching the four MPI constants (MPI_THREAD_SINGLE, …, MPI_THREAD_MULTIPLE).

This implementation is thread-safe throughout and always provides Threading::Multiple; the requested level is recorded for compatibility.

Variants

Single

Only one thread will execute (MPI_THREAD_SINGLE).

Funneled

The process may be multithreaded, but only the main thread makes MPI calls (MPI_THREAD_FUNNELED).

Serialized

Multiple threads may make MPI calls, but not concurrently (MPI_THREAD_SERIALIZED).

Multiple

Multiple threads may call MPI concurrently (MPI_THREAD_MULTIPLE).

Implementations

impl Threading

pub const fn max() -> Threading

The maximum thread-support level this library provides.

Trait Implementations

impl Clone for Threading

fn clone(&self) -> Threading

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Threading

impl Debug for Threading

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

Formats the value using the given formatter.

impl Eq for Threading

impl Ord for Threading

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

fn eq(&self, other: &Threading) -> 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 Threading

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