+# const-fnv1a-hash
+Rust based const FNV1A hashing implementation for hashing at compile time. 
+
+This is a Rust implementation of FNV1A hashing algorithms which works on the stable channel.
+
+# Features
+- no_std.
+- All functions are const, and can be used at compile time to hash all the things.
+- Additional convenience functions for str hashing.
+- dependency free.
+- 16 bit hashing implemented using XOR folding.
