Struct InteriorMut

pub struct InteriorMut<'tcx> {
    ignored_def_ids: FxHashSet<DefId>,
    ignore_pointers: bool,
    tys: FxHashMap<Ty<'tcx>, Option<&'tcx List<Ty<'tcx>>>>,
}

Helper to check if given type has inner mutability such as std::cell::Cell or std::cell::RefCell.

Fields

ignored_def_ids: FxHashSet<DefId>

ignore_pointers: bool

tys: FxHashMap<Ty<'tcx>, Option<&'tcx List<Ty<'tcx>>>>

Implementations

impl<'tcx> InteriorMut<'tcx>

pub fn new(tcx: TyCtxt<'tcx>, ignore_interior_mutability: &[String]) -> Self

pub fn without_pointers( tcx: TyCtxt<'tcx>, ignore_interior_mutability: &[String], ) -> Self

pub fn interior_mut_ty_chain( &mut self, cx: &LateContext<'tcx>, ty: Ty<'tcx>, ) -> Option<&'tcx List<Ty<'tcx>>>

Check if given type has interior mutability such as std::cell::Cell or std::cell::RefCell etc. and if it does, returns a chain of types that causes this type to be interior mutable

pub fn is_interior_mut_ty( &mut self, cx: &LateContext<'tcx>, ty: Ty<'tcx>, ) -> bool

Check if given type has interior mutability such as std::cell::Cell or std::cell::RefCell etc.

Trait Implementations

impl<'tcx> Debug for InteriorMut<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Default for InteriorMut<'tcx>

fn default() -> InteriorMut<'tcx>

Returns the “default value” for a type.

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.
