Martin Habovstiak	6fc4860813	Activate `rust_v_1_46` when on high-enough rustc ... This adds a build script that automatically activates the cfg if the version is sufficient. We don't make API changes here, just improve debugging by enabling `track_caller`.	2022-09-14 08:55:02 +02:00
Martin Habovstiak	040b14ef1a	Implement basic support for fast hex encoding ... 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`.	2022-09-13 22:17:31 +02:00
Tobin C. Harding	834bbf461f	Introduce bitcoin-internals crate ... Add a new crate `bitcoin-internals` to be used for internal code needed by multiple soon-to-be-created crates. Add the `write_err` macro to `bitcoin-internals`, nothing else. This patch uses a `path` dependency which means `rust-bitcoin` cannot be released in its current state, will need to be changed once we release the `bitcoin-internals` crate on `crates.io`.	2022-09-13 08:59:57 +10:00
