Struct FnMutDelegate 

pub struct FnMutDelegate<'a, 'tcx> {
    pub regions: &'a mut (dyn FnMut(BoundRegion) -> Region<'tcx> + 'a),
    pub types: &'a mut (dyn FnMut(BoundTy) -> Ty<'tcx> + 'a),
    pub consts: &'a mut (dyn FnMut(BoundConst) -> Const<'tcx> + 'a),
}

A simple delegate taking 3 mutable functions. The used functions must always return the same result for each bound variable, no matter how frequently they are called.

Fields

regions: &'a mut (dyn FnMut(BoundRegion) -> Region<'tcx> + 'a)

types: &'a mut (dyn FnMut(BoundTy) -> Ty<'tcx> + 'a)

consts: &'a mut (dyn FnMut(BoundConst) -> Const<'tcx> + 'a)

Trait Implementations

impl<'a, 'tcx> BoundVarReplacerDelegate<'tcx> for FnMutDelegate<'a, 'tcx>

fn replace_region(&mut self, br: BoundRegion) -> Region<'tcx>

fn replace_ty(&mut self, bt: BoundTy) -> Ty<'tcx>

fn replace_const(&mut self, bc: BoundConst) -> Const<'tcx>

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.
