this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

OnDiskCache provides an interface to incr. comp. data cached from the previous compilation session. This data will eventually include the results of a few selected queries (like typeck_tables_of and mir_optimized) and any diagnostics that have been emitted during a query.

Returns the cached query result if there is something in the cache for the given SerializedDepNodeIndex. Otherwise returns None.

Store a diagnostic emitted during computation of an anonymous query. Since many anonymous queries can share the same DepNode, we aggregate them -- as opposed to regular queries where we assume that there is a 1:1 relationship between query-key and DepNode.
