RevSegIdx

rustc_hir_analysis::collect::resolve_bound_vars

Struct RevSegIdx 

Source 
struct RevSegIdx(usize);
Expand description

A reversed path segment index.

E.g., for qualified path <() as path::to::TraitRef<…>>::AssocTy<…> the mapping from reversed index to path segment would look like 3 ↦ path, 2 ↦ to, 1 ↦ TraitRef<…>, 0 ↦ AssocTy<…>.
