Function rustc::middle::resolve_lifetime::free_lifetimes[src]
pub fn free_lifetimes(ty_params: &OwnedSlice<TyParam>) -> Vec<Name>
Gathers up and returns the names of any lifetimes that appear
free in ty_params. Of course, right now, all lifetimes appear
free, since we don't currently have any binders in type parameter
declarations; just being forwards compatible with future extensions.
