| Name| Description
| xref:BloombergLP/bslstp/Hash-09.adoc[`Hash`] 
| Empty base class for hashing. No general hash struct defined, each type requires a specialization. Leaving this struct declared but undefined will generate error messages that are more clear when someone tries to use a key that does not have a corresponding hash function.
| xref:BloombergLP/bslstp/HashCString.adoc[`HashCString`] 
| Hash functor to generate a hash for a pointer to a null‐terminated string.
| xref:BloombergLP/bslstp/HashSelector-04.adoc[`HashSelector`] 
| This meta‐function selects the appropriate implementation for comparing the parameterized `TYPE`. This generic template uses the `std::equal_to` functor.
| xref:BloombergLP/bslstp/Identity.adoc[`Identity`] 
| An identity function.
| xref:BloombergLP/bslstp/Util.adoc[`Util`] 
| Namespace for utility functions used to implement STL functionality.
