pub struct Options { /* private fields */ }
Expand description
Control struct for searching type parameters.
This acts as the search context, preserving information that might have been
kept on a visitor in a different implementation.
Trait implementers are required to pass this through on any invocations they make.
For extensibility, Options
hides all of its fields from consumers.
To create an instance, use the From<Purpose>
trait implementation:
let opts: Options = Purpose::BoundImpl.into();
assert!(!opts.include_type_path_qself());
Returns true
if the implementer of UseTypeParams
should search
<___ as ...>::...
when looking for type parameter uses.
