tag! and byte arrays

[niclashoyer]

What is the correct way to use tag! with a fixed byte array? tag!([42u8, 42u8]) fails, as AsBytes is not implemented for [u8; 2].

Well, you can do tag!(&[42u8, 42u8][..]) but it looks very ugly 😒

Could you wait a bit? I'm writing the AsBytes implementation for fixed length arrays.

Of course 😄
Is it true, that there is no simpler way than implementing the same method for every fixed size [T; 0], [T; 1], ...? At least it is done this way in std::array. Seems very tedious.

There are lots of cases like this in language development, any time something has a fixed number of components, like tuples or function arguments.

Oddly, it is easier to handle an array of unknown length.

I just published nom 0.3.7, this should work now. Let me know if you need anything else!

works like a charm, thanks!
