I have this code:
func my_function(hash string) [16]byte {
b, _ := hex.DecodeString(hash)
return b // Compile error: fails since [16]byte != []byte
}
b
will be of type []byte
. I know that hash
is of length 32. How can I make my code above work? Ie. can I somehow cast from a general-length byte array to a fixed-length byte array? I am not interested in allocating 16 new bytes and copying the data over.
