Struct miri::Stacks

pub struct Stacks {
    stacks: RangeMap<Stack>,
    history: AllocHistory,
    exposed_tags: FxHashSet<SbTag>,
}

Extra per-allocation state.

Fields

stacks: RangeMap<Stack>

history: AllocHistory

Stores past operations on this allocation

exposed_tags: FxHashSet<SbTag>

The set of tags that have been exposed inside this allocation.

Implementations

impl<'tcx> Stacks

Map per-stack operations to higher-level per-location-range operations.

fn new(size: Size, perm: Permission, tag: SbTag) -> Self

Creates new stack with initial tag.

fn for_each(
    &mut self,
    range: AllocRange,
    f: impl FnMut(Size, &mut Stack, &mut AllocHistory, &mut FxHashSet<SbTag>) -> InterpResult<'tcx>
) -> InterpResult<'tcx>

Call f on every stack in the range.

Trait Implementations

impl Clone for Stacks

fn clone(&self) -> Stacks

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Stacks

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

Formats the value using the given formatter.

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.
