pub struct BuildHasherDefault<H>(/* private fields */);Expand description
Used to create a default BuildHasher instance for types that implement
Hasher and Default.
BuildHasherDefault<H> can be used when a type H implements Hasher and
Default, and you need a corresponding BuildHasher instance, but none is
defined.
Any BuildHasherDefault is zero-sized. It can be created with
default. When using BuildHasherDefault with HashMap or
HashSet, this doesn’t need to be done, since they implement appropriate
Default instances themselves.
