Function find_anon_type

Source 
pub fn find_anon_type<'tcx>(
    tcx: TyCtxt<'tcx>,
    generic_param_scope: LocalDefId,
    region: Region<'tcx>,
    br: &BoundRegionKind,
) -> Option<(&'tcx Ty<'tcx>, &'tcx FnSig<'tcx>)>
Expand description

This function calls the visit_ty method for the parameters corresponding to the anonymous regions. The nested_visitor.found_type contains the anonymous type.

§Arguments

region - the anonymous region corresponding to the anon_anon conflict br - the bound region corresponding to the above region which is of type BrAnon(_)

§Example

ⓘ
fn foo(x: &mut Vec<&u8>, y: &u8)
   { x.push(y); }

The function returns the nested type corresponding to the anonymous region for e.g., &u8 and Vec<&u8>.
