TryInto is already implemented for slices in 1.47, so `let foo = u16::from_be_bytes(some_slice.try_into().unwrap());` would work before 1.48.

This trait wasn't implemented for vectors though, so you would have to write `let foo = u16::from_be_bytes(some_vec.to_slice().try_into().unwrap());`.

With new release you can drop `to_slice()` part. Nothing earth-shattering, but makes sense.

Rustdocs say it was 1.36 even? https://doc.rust-lang.org/nightly/std/primitive.array.html#i...

Yeah, by "In 1.47" I mean that as of 1.47 it was already implemented, didn't check since which version.

Ah fun! I missed that. Time to clean up some code...

That doesn't work with non-copyable types.
