Struct ParamFinder 

struct ParamFinder {
    params: Vec<Symbol>,
}

Look for type parameters in predicates. We use this to identify whether a bound is suitable in on a given item.

Fields

params: Vec<Symbol>

Implementations

impl ParamFinder

fn can_suggest_bound(&self, generics: &Generics<'_>) -> bool

Whether the hir::Generics of the current item can suggest the evaluated bound because its references to type parameters are present in the generics.

Trait Implementations

impl<'tcx> TypeVisitor<TyCtxt<'tcx>> for ParamFinder

fn visit_ty(&mut self, t: Ty<'tcx>) -> Self::Result

type Result = ()

fn visit_binder<T>(&mut self, t: &Binder<I, T>) -> Self::Result

where T: TypeVisitable<I>,

fn visit_region(&mut self, r: <I as Interner>::Region) -> Self::Result

fn visit_const(&mut self, c: <I as Interner>::Const) -> Self::Result

fn visit_predicate(&mut self, p: <I as Interner>::Predicate) -> Self::Result

fn visit_clauses(&mut self, c: <I as Interner>::Clauses) -> Self::Result

fn visit_error( &mut self, _guar: <I as Interner>::ErrorGuaranteed, ) -> Self::Result

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.
