Provided Methods

fn tb_reborrow( &mut self, place: &MPlaceTy<'tcx>, ptr_size: Size, new_perm: NewPermission, new_tag: BorTag, ) -> InterpResult<'tcx, Option<Provenance>>

Returns the provenance that should be used henceforth.

fn tb_retag_place( &mut self, place: &MPlaceTy<'tcx>, new_perm: NewPermission, ) -> InterpResult<'tcx, MPlaceTy<'tcx>>

fn tb_retag_reference( &mut self, val: &ImmTy<'tcx>, new_perm: NewPermission, ) -> InterpResult<'tcx, ImmTy<'tcx>>

Retags an individual pointer, returning the retagged version.

Implementors

impl<'tcx> EvalContextPrivExt<'tcx> for MiriInterpCx<'tcx>

Retagging/reborrowing. Policy on which permission to grant to each pointer should be left to the implementation of NewPermission.
