Struct GenericsSubstFolder

pub(crate) struct GenericsSubstFolder<'a, D> {
    current_index: DebruijnIndex,
    delegate: D,
    refinement_args: &'a [Expr],
}

Substitution for generics, i.e., early bound types, lifetimes, const generics, and refinements. Note that a substitution for refinement parameters (a list of expressions) must always be specified, while the behavior of other generics parameters (types, lifetimes and consts) can be configured with GenericsSubstDelegate.

Fields

current_index: DebruijnIndex

delegate: D

refinement_args: &'a [Expr]
