Struct minstant::Atomic

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

Available on crate feature atomic and target_has_atomic="64" only.

Atomic variant of Instant.

Implementations

impl Atomic

pub fn fetch_max(&self, val: Instant, order: Ordering) -> Instant

Maximum with the current value.

Finds the maximum of the current value and the argument val, and sets the new value to the result.

Returns the previous value.

fetch_max takes an Ordering argument which describes the memory ordering of this operation. All ordering modes are possible. Note that using Acquire makes the store part of this operation Relaxed, and using Release makes the load part Relaxed.

Note: This method is only available on platforms that support atomic operations on [u64].

pub fn fetch_min(&self, val: Instant, order: Ordering) -> Instant

Minimum with the current value.

Finds the minimum of the current value and the argument val, and sets the new value to the result.

Returns the previous value.

fetch_min takes an Ordering argument which describes the memory ordering of this operation. All ordering modes are possible. Note that using Acquire makes the store part of this operation Relaxed, and using Release makes the load part Relaxed.

Note: This method is only available on platforms that support atomic operations on [u64].

pub fn into_instant(self) -> Instant

Consumes the atomic and returns the contained Instant.

This is safe because passing self by value guarantees that no other threads are concurrently accessing the atomic data.

pub fn load(&self, order: Ordering) -> Instant

Loads a value from the Atomic.

load takes an Ordering argument which describes the memory ordering of this operation. Possible values are SeqCst, Acquire and Relaxed.

Panics

Panics if order is Release or AcqRel.

pub fn new(v: Instant) -> Self

Creates a new Atomic.

pub fn store(&self, val: Instant, order: Ordering)

Stores a value into the Atomic.

store takes an Ordering argument which describes the memory ordering of this operation. Possible values are SeqCst, Release and Relaxed.

Panics

Panics if order is Acquire or AcqRel.

pub fn swap(&self, val: Instant, order: Ordering) -> Instant

Stores a value into the Atomic, returning the previous value.

swap takes an Ordering argument which describes the memory ordering of this operation. All ordering modes are possible. Note that using Acquire makes the store part of this operation Relaxed, and using Release makes the load part Relaxed.

Note: This method is only available on platforms that support atomic operations on u64

Trait Implementations

impl Debug for Atomic

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

Formats the value using the given formatter.

impl From<Instant> for Atomic

fn from(instant: Instant) -> Self

Converts to this type from the input type.
