Implementations

impl AllocState

pub fn before_memory_read<'tcx>( &self, alloc_id: AllocId, prov_extra: ProvenanceExtra, range: AllocRange, machine: &MiriMachine<'tcx>, ) -> InterpResult<'tcx>

pub fn before_memory_write<'tcx>( &mut self, alloc_id: AllocId, prov_extra: ProvenanceExtra, range: AllocRange, machine: &MiriMachine<'tcx>, ) -> InterpResult<'tcx>

pub fn before_memory_deallocation<'tcx>( &mut self, alloc_id: AllocId, prov_extra: ProvenanceExtra, size: Size, machine: &MiriMachine<'tcx>, ) -> InterpResult<'tcx>

pub fn remove_unreachable_tags(&self, tags: &FxHashSet<BorTag>)

pub fn release_protector<'tcx>( &self, machine: &MiriMachine<'tcx>, global: &RefCell<GlobalStateInner>, tag: BorTag, alloc_id: AllocId, ) -> InterpResult<'tcx>

Tree Borrows needs to be told when a tag stops being protected.
