Oh nice - I didn't know TryInto implemented this! Fantastic, one less unsafe dependency. |

Title pretty much says it all. We were only using on one line, to get the first 32 bytes of a key for Diffe-Hellman 25519. Since Rust 1.34, TryInto works for turning slices into arrays, as noted here. 32 bytes is the limit until const generics, but conveniently 32 is all we need for this.
Overall, seems a tad overkill to bring in an entire library for one line that Rust core functionality offers.
