Expand description

Requirements for a StableHashingContext to be used in this crate.

This is a hack to allow using the HashStable_Generic derive macro instead of implementing everything in rustc_middle.

Required Methods§

Accesses sess.opts.unstable_opts.incremental_ignore_spans since we don’t have easy access to a Session
