Provided Methods

fn expose_ptr(&mut self, alloc_id: AllocId, tag: BorTag) -> InterpResult<'tcx>

fn ptr_from_addr_cast(&self, addr: u64) -> InterpResult<'tcx, Pointer>

fn adjust_alloc_root_pointer( &self, ptr: Pointer<CtfeProvenance>, tag: BorTag, kind: MemoryKind, ) -> InterpResult<'tcx, Pointer<Provenance>>

Convert a relative (tcx) pointer to a Miri pointer.

fn get_global_alloc_bytes( &self, id: AllocId, kind: MemoryKind, bytes: &[u8], align: Align, ) -> InterpResult<'tcx, MiriAllocBytes>

fn ptr_get_alloc( &self, ptr: Pointer<Provenance>, size: i64, ) -> Option<(AllocId, Size)>

When a pointer is used for a memory access, this computes where in which allocation the access is going.
