:mrdocs:

Partial specialization that hashes `const` types as their non‐`const` type.

== Synopsis

Declared in `<bslstp_hash.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----

struct xref:BloombergLP/bslstp/HashSelector-04.adoc[HashSelector]<HASH_KEY const>;
----

== Description

Treat `const` qualified types in exactly the same way as the non‐`const` qualified type. Users should rarely, if ever, need this specialization but would be surprised by their results if used accidentally, and it were not supplied.
