:relfileprefix: ../../
:mrdocs:

Create a new `HashState` instance that wraps `state`.

== Synopsis

Declared in `<absl/hash/hash.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<typename T>
requires std::is_base_of_v<hash_internal::HashStateBase<T>, T>
static
xref:absl/HashState.adoc[HashState]
Create(T* state);
----

== Description

All calls to `combine()` and `combine_contiguous()` on the new instance will be redirected to the original `state` object. The `state` object must outlive the `HashState` instance. `T` must be a subclass of `HashStateBase<T>` ‐ users should not define their own HashState types.

== Return Value

A type‐erased `HashState` wrapping `state`.

== Parameters
