There's a `hex` module in `bitcoin_hashes` which is a bit out of place and not very fast - it passes each *digit* through dynamic dispatch not only adding overhead but also not allowing `String` to make better allocations. This change adds basic support for hex encoding using a stack-allocated buffer which minimizes the overhead of dynamic dispatch. It also provides a new `DisplayHex` trait designed to replace `ToHex` found in `bitcoin_hashes`. |
