Passes the specified input into the specified hashAlg to be combined into the internal state of the algorithm which is used to produce the resulting hash value. Note that the enable_if meta‐function is used to enable this hashAppend function for only integral (excluding bool), pointer, and enum types, because these types can all be hashed as a continuous sequence of bytes. Also note that this function is defined inline because MS Visual Studio compilers before 2013 require (some) functions declared using enable_if be in‐place inline.
