rust/src/test/auxiliary/lifetime_bound_will_change_warning_lib.rs
Niko Matsakis 1e7a6b880c After inferring regions, scan for any bounds that are due to a lifetime
bound that is likely to change. In that case, it will change to 'static,
so then scan down the graph to see whether there are any hard
constraints that would prevent 'static from being a valid value
here. Report a warning.
