Struct ThreadClockSet

pub(super) struct ThreadClockSet {
    pub(super) clock: VClock,
    fence_acquire: VClock,
    fence_release: VClock,
    pub(super) write_seqcst: VClock,
    pub(super) read_seqcst: VClock,
}

The current set of vector clocks describing the state of a thread, contains the happens-before clock and additional metadata to model atomic fence operations.

Fields

clock: VClock

The increasing clock representing timestamps that happen-before this thread.

fence_acquire: VClock

The set of timestamps that will happen-before this thread once it performs an acquire fence.

fence_release: VClock

The last timestamp of happens-before relations that have been released by this thread by a release fence.

write_seqcst: VClock

Timestamps of the last SC write performed by each thread, updated when this thread performs an SC fence. This is never acquired into the thread’s clock, it just limits which old writes can be seen in weak memory emulation.

read_seqcst: VClock

Timestamps of the last SC fence performed by each thread, updated when this thread performs an SC read. This is never acquired into the thread’s clock, it just limits which old writes can be seen in weak memory emulation.

Implementations

impl ThreadClockSet

fn apply_release_fence(&mut self)

Apply the effects of a release fence to this set of thread vector clocks.

fn apply_acquire_fence(&mut self)

Apply the effects of an acquire fence to this set of thread vector clocks.

fn increment_clock(&mut self, index: VectorIdx, current_span: Span)

Increment the happens-before clock at a known index.

fn join_with(&mut self, other: &ThreadClockSet)

Join the happens-before clock with that of another thread, used to model thread join operations.

Trait Implementations

impl Clone for ThreadClockSet

fn clone(&self) -> ThreadClockSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadClockSet

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

Formats the value using the given formatter.

impl Default for ThreadClockSet

fn default() -> ThreadClockSet

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
