-WARNING
--------
-
-`TypeStructure<T>` and the `type_structure()` API are experimental
-features of HHVM, and not supported. Expect them to break with some future
-HHVM release.
-
-This library uses them anyway as there is not currently an alternative
-way to do this.
+See [the TypeAssert class](https://github.com/fredemmott/type-assert/blob/master/src/TypeAssert.php) for full API.
