Struct Options

pub struct Options { /* private fields */ }

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.

Usage

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());

Implementations

impl Options

pub fn include_type_path_qself(&self) -> bool

Returns true if the implementer of UseTypeParams should search <___ as ...>::... when looking for type parameter uses.
