Expand description

Searcher for finding type params in a syntax tree. This can be used to determine if a given type parameter needs to be bounded in a generated impl.

Required methods

fn uses_type_params(
    &self,
    options: &Options,
    type_set: &'a HashSet<Ident, BuildHasherDefault<FnvHasher>>
) -> HashSet<&'a Ident, BuildHasherDefault<FnvHasher>>[src]

Returns the subset of the queried type parameters that are used by the implementing syntax element.

This method only accounts for direct usage by the element; indirect usage via bounds or where predicates are not detected.

Provided methods

fn uses_type_params_cloned(
    &self,
    options: &Options,
    type_set: &HashSet<Ident, BuildHasherDefault<FnvHasher>>
) -> HashSet<Ident, BuildHasherDefault<FnvHasher>>[src]

Find all type params using uses_type_params, then clone the found values and return the set.
