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§
sourcefn uses_type_params<'a>(
&self,
options: &Options,
type_set: &'a IdentSet
) -> IdentRefSet<'a>
fn uses_type_params<'a>( &self, options: &Options, type_set: &'a IdentSet ) -> IdentRefSet<'a>
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§
sourcefn uses_type_params_cloned(
&self,
options: &Options,
type_set: &IdentSet
) -> IdentSet
fn uses_type_params_cloned( &self, options: &Options, type_set: &IdentSet ) -> IdentSet
Find all type params using uses_type_params
, then clone the found values and return the set.
