Struct DefaultHashBuilder 

pub struct DefaultHashBuilder(pub(crate) RandomState);

The default BuildHasher used by the cache.

The hashing algorithm behind this type is an implementation detail and may change in any release. Name this type — don’t rely on the concrete hasher it wraps. The underlying hasher is selected by the custom-hasher feature (a fast non-cryptographic hasher when enabled, the std library’s RandomState otherwise).
