Function fn_generic_params 

Source 
fn fn_generic_params(
    make: &SyntaxFactory,
    ctx: &AssistContext<'_, '_>,
    necessary_params: FxHashSet<GenericParam>,
    target: &GeneratedFunctionTarget,
) -> Option<(Option<GenericParamList>, Option<WhereClause>)>
Expand description

Gets parameter bounds and where predicates in scope and filters out irrelevant ones. Returns None when it fails to get scope information.

See comment on filter_unnecessary_bounds() for what bounds we consider relevant.

NOTE: Generic parameters returned from this function may cause name clash at target. We don’t currently do anything about it because it’s actually easy to resolve it after the assist: just use the Rename functionality.
