 It is not a general-use HashMap and currently has slow write performance for write heavy uses.
 
-The minimal supported Golang version is 1.19 as it makes use of Generics and the new atomic package helpers.

 Reading from the hash map for numeric key types in a thread-safe way is faster than reading from a standard Golang map
