Implementations

impl<'mir, 'tcx: 'mir> StoreBuffer

fn new(init: Scalar<Provenance>) -> Self

fn read_from_last_store( &self, global: &DataRaceState, thread_mgr: &ThreadManager<'_, '_>, is_seqcst: bool )

Reads from the last store in modification order

fn buffered_read( &self, global: &DataRaceState, thread_mgr: &ThreadManager<'_, '_>, is_seqcst: bool, rng: &mut (impl Rng + ?Sized), validate: impl FnOnce() -> InterpResult<'tcx> ) -> InterpResult<'tcx, (Scalar<Provenance>, LoadRecency)>

fn buffered_write( &mut self, val: Scalar<Provenance>, global: &DataRaceState, thread_mgr: &ThreadManager<'_, '_>, is_seqcst: bool ) -> InterpResult<'tcx>

fn fetch_store<R: Rng + ?Sized>( &self, is_seqcst: bool, clocks: &ThreadClockSet, rng: &mut R ) -> (&StoreElement, LoadRecency)

Selects a valid store element in the buffer.

fn store_impl( &mut self, val: Scalar<Provenance>, index: VectorIdx, thread_clock: &VClock, is_seqcst: bool )

ATOMIC STORE IMPL in the paper (except we don’t need the location’s vector clock)

Trait Implementations

impl Clone for StoreBuffer

fn clone(&self) -> StoreBuffer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StoreBuffer

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

Formats the value using the given formatter.

impl PartialEq<StoreBuffer> for StoreBuffer

fn eq(&self, other: &StoreBuffer) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for StoreBuffer

impl StructuralEq for StoreBuffer

impl StructuralPartialEq for StoreBuffer

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.
