+*  XXH3
+*  New experimental hash
+************************************************************************/
+#ifndef XXH_NO_LONG_LONG
+
+
+/* ============================================
+ * XXH3 is a new hash algorithm,
+ * featuring improved speed performance for both small and large inputs.
+ * See full speed analysis at : http://fastcompression.blogspot.com/2019/03/presenting-xxh3.html
+ * In general, expect XXH3 to run about ~2x faster on large inputs,
+ * and >3x faster on small ones, though exact differences depend on platform.
+ *
+ * The algorithm is portable, will generate the same hash on all platforms.
+ * It benefits greatly from vectorization units, but does not require it.
+ *
+ * XXH3 offers 2 variants, _64bits and _128bits.
+ * When only 64 bits are needed, prefer calling the _64bits variant :
+ * it reduces the amount of mixing, resulting in faster speed on small inputs.
+ * It's also generally simpler to manipulate a scalar return type than a struct.
+ *
+ * The XXH3 algorithm is still considered experimental.
+ * Produced results can still change between versions.
+ * For example, results produced by v0.7.1 are not comparable with results from v0.7.0 .
+ * It's nonetheless possible to use XXH3 for ephemeral data (local sessions),
+ * but avoid storing values in long-term storage for later re-use.
+ *
+ * The API supports one-shot hashing, streaming mode, and custom secrets.
+ *
+ * There are still a number of opened questions that community can influence during the experimental period.
+ * I'm trying to list a few of them below, though don't consider this list as complete.
+ *
+ * - 128-bits output type : currently defined as a structure of two 64-bits fields.
+ *                          That's because 128-bit values do not exist in C standard.
+ *                          Note that it means that, at byte level, result is not identical depending on endianess.
+ *                          However, at field level, they are identical on all platforms.
+ *                          The canonical representation solves the issue of identical byte-level representation across platforms,
+ *                          which is necessary for serialization.
+ *                          Would there be a better representation for a 128-bit hash result ?
+ *                          Are the names of the inner 64-bit fields important ? Should they be changed ?
+ *
+ * - Seed type for 128-bits variant : currently, it's a single 64-bit value, like the 64-bit variant.
+ *                          It could be argued that it's more logical to offer a 128-bit seed input parameter for a 128-bit hash.
+ *                          But 128-bit seed is more difficult to use, since it requires to pass a structure instead of a scalar value.
+ *                          Such a variant could either replace current one, or become an additional one.
+ *                          Farmhash, for example, offers both variants (the 128-bits seed variant is called `doubleSeed`).
+ *                          If both 64-bit and 128-bit seeds are possible, which variant should be called XXH128 ?
+ *
+ * - Result for len==0 : Currently, the result of hashing a zero-length input is `0`.
+ *                          It seems okay as a return value when using all "default" secret and seed (it used to be a request for XXH32/XXH64).
+ *                          But is it still fine to return `0` when secret or seed are non-default ?
+ *                          Are there use cases which could depend on generating a different hash result for zero-length input when the secret is different ?
