Trait Implementations

impl Debug for DropShimElaborator<'_, '_>

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

Formats the value using the given formatter.

impl<'a, 'tcx> DropElaborator<'a, 'tcx> for DropShimElaborator<'a, 'tcx>

type Path = ()

The type representing paths that can be moved out of.

fn patch(&mut self) -> &mut MirPatch<'tcx>

fn body(&self) -> &'a Body<'tcx>

fn tcx(&self) -> TyCtxt<'tcx>

fn param_env(&self) -> ParamEnv<'tcx>

fn drop_style(&self, _path: Self::Path, mode: DropFlagMode) -> DropStyle

Returns how path should be dropped, given mode.

fn get_drop_flag(&mut self, _path: Self::Path) -> Option<Operand<'tcx>>

Returns the drop flag of path as a MIR Operand (or None if path has no drop flag).

fn clear_drop_flag( &mut self, _location: Location, _path: Self::Path, _mode: DropFlagMode )

Modifies the MIR patch so that the drop flag of path (if any) is cleared at location.

fn field_subpath( &self, _path: Self::Path, _field: FieldIdx ) -> Option<Self::Path>

Returns the subpath of a field of path (or None if there is no dedicated subpath).

fn deref_subpath(&self, _path: Self::Path) -> Option<Self::Path>

Returns the subpath of a dereference of path (or None if there is no dedicated subpath).

fn downcast_subpath( &self, _path: Self::Path, _variant: VariantIdx ) -> Option<Self::Path>

Returns the subpath of downcasting path to one of its variants.

fn array_subpath( &self, _path: Self::Path, _index: u64, _size: u64 ) -> Option<Self::Path>

Returns the subpath of indexing a fixed-size array path.

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.
