Hello,
I can print slices of bytes as hex strings, using code like the following:
x := []byte{0, 1, 2, 3}
fmt.Printf("%02x", x[:l])
This gives the output "00010203" as expected. But this fails for the empty
slice: running
x := []byte{}
fmt.Printf("%02x", x[:l])
gives "00" instead of the empty string. See
https://play.golang.org/p/rvLLqydDDE6 for a demonstration.
Is this a bug, or is this expected behaviour?
All the best,
Jochen
