pub struct Stacks {
stacks: RangeMap<Stack>,
history: AllocHistory,
exposed_tags: FxHashSet<BorTag>,
}
Expand description
Extra per-allocation state.
Fields§
§stacks: RangeMap<Stack>
§history: AllocHistory
Stores past operations on this allocation
The set of tags that have been exposed inside this allocation.
Implementations§
Source§impl<'tcx> Stacks
Map per-stack operations to higher-level per-location-range operations.
impl<'tcx> Stacks
Map per-stack operations to higher-level per-location-range operations.
Sourcefn new(
size: Size,
perm: Permission,
tag: BorTag,
id: AllocId,
machine: &MiriMachine<'_>,
) -> Self
fn new( size: Size, perm: Permission, tag: BorTag, id: AllocId, machine: &MiriMachine<'_>, ) -> Self
Creates a new stack with an initial tag. For diagnostic purposes, we also need to know
the AllocId
of the allocation this is associated with.
Sourcefn for_each(
&mut self,
range: AllocRange,
dcx_builder: DiagnosticCxBuilder<'_, 'tcx>,
f: impl FnMut(&mut Stack, &mut DiagnosticCx<'_, '_, 'tcx>, &mut FxHashSet<BorTag>) -> InterpResult<'tcx>,
) -> InterpResult<'tcx>
fn for_each( &mut self, range: AllocRange, dcx_builder: DiagnosticCxBuilder<'_, 'tcx>, f: impl FnMut(&mut Stack, &mut DiagnosticCx<'_, '_, 'tcx>, &mut FxHashSet<BorTag>) -> InterpResult<'tcx>, ) -> InterpResult<'tcx>
Call f
on every stack in the range.

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.
