When encoding a `network::Address` two of the fields are encoded
big-endian instead of little-endian as is done by `consensus_encode`. In
order to achieve this we have a helper function `addr_to_be` that swaps
the bytes. This function is miss-named because it is not converting to a
specific endian-ness (which implies different behaviour on machines with
different endian-ness) but is reversing the byte order irrespective of
the underlying architecture.
- Remove function `addr_to_be`
- Inline the endian-ness code when encoding an address
- Remove TODO and use `to_be_bytes` when encoding port
- Add a function for reading big-endian bytes `read_be_address`
- Use `read_be_address` when decoding `Address` and `Addrv2`
Refactor only, no logic changes. Code path is already covered by
unit tests.
The Lightning network defines a type called 'chain hash' that is used to
uniquely represent the various Bitcoin networks as a 32 byte hash value.
Chain hash is now being used by the DLC folks, as such it is useful to
have it implemented in rust-bitcoin.
One method of calculating a chain hash is by hashing the genesis block
for the respective network.
Add a `ChainHash` type that can be used to get the unique identifier of
each of the 4 Bitcoin networks we support. Add a method that returns
the chain hash for a network using the double sha256 of the genesis
block. Do so using hard coded consts and add unit
tests (regression/sanity) that show these hard code byte arrays match
the hash of the data we return for the genesis block for the respective
network.
The chain hash for the main Bitcoin network can be verified from LN
docs (BOLT 0), add a link to this document.
Since commit `commit 275adc6c335a4326699cfbd444949e1725864ea1` on
`bitcoin_hashes` we have the identical implementation of the macro
`sha256t1_hash_newtype` in this crate and in `bitcoin_hashes`.
Remove the `sha256t_hash_newtype` macro from this crate in favour of the
one in `bitcoin_hashes`.
Clippy emits warning:
public documentation for `script_leaves` links to private item `TapTreeIter`
I'm not exactly sure why this is but adding the generic type place
holder clears the warning.
Improve documentation in `psbt/mod.rs` by doing:
- Use full sentences (full stops and capitalisation)
- Use 100 line column width
- Use back ticks and links as appropriate
- Use `Errors` section
- Use third person tense to describe functions
Improve the rustdoc documentation in the `sighash` module by doing:
- Improve grammar
- Use full sentences (full stops and capitalisation)
- Use 100 line column width
- Use back ticks and links as appropriate
- Improve correctness of `SigHashCache::new` function
9f0c687d89 Enable edition 2018 (Tobin C. Harding)
dca0d67771 Fix in preparation for next edition (Tobin C. Harding)
Pull request description:
This PR supersedes #635 at the permission of @Kixunil in the thread of that PR.
Do a minimal set of changes to enable edition 2018. Patch 1 is the biggest change set, it is done with `cargo`, no other manual changes are included in patch 1. It can verified by running `cargo fix --edition` on master and checking the diffs are the same.
Patch 2 enables 2018 and includes all the manual changes required to get the code to build (with _all_ the feature combinations :)

0ab5eeac81 Add method to push an ECDSA sig + sighash type byte on a witness (Matt Corallo)
Pull request description:
We do this all over the place in rust-lightning, and its probably
the most common thing to do with a `Witness` so I figured I'd
upstream the util method to do this. It also avoids an allocation
compared to the naive approach of `SerializedSignature.to_vec()`
with two pushes, which is nice.

4f1200d629 Added `amount::Display` - configurable formatting (Martin Habovstiak)
Pull request description:
This significatnly refactors the formatting code to make formatting more
configurable. The main addition is the `Display` type which is a
builder that can configure denomination or other things (possibly more
in the future).
Further, this makes all representations of numbers minimal by default,
so should be documented as a possibly-breaking change.
Because of the effort to support all other `fmt::Formatter` options this
required practically complete rewrite of `fmt_satoshi_in`. As a
byproduct I took the opportunity of removing one allocation from there.

Pull request description:
This refactors `blockdata::script::Instructions` to use
`::core::slice::Iter<'a, u8>` instead of `&'a [u8]` to better express
the intention and to avoid some slicing mistakes. Similarly to a
previous change this uses a macro to deduplicate the common logic and
the new `read_uint_iter` internal function to automatically advance the
iterator.

7854bd7918 Fix `no_std` MSRV Fixes#690, #947 (mcroad)
Pull request description:
`rust-bitcoin` does not work with rust 1.29 under a `no_std` environment. This could be considered a bug. However, `no_std` support is a recent addition and this is likely not breaking anyone's builds.
A decision needs to be made, either `no_std` MSRV is the current stable version while keeping the `std` MSRV as 1.29, or it needs to be fixed.
This pr adds `no_std` to the 1.29 test suite.
This came as I try to get rust-bitcoin/rust-miniscript#277 working and got stuck on the issue of testing `no_std` under 1.29.

We do not need serde/std, only serde/alloc. Serde/std breaks no-std
builds, but serde/alloc does not. Depending on serde/alloc is the more
compatible approach, as the entire library already depends on alloc.

It is more typical in this repo to use `module::Error` instead of a type
alias when importing.
Use `hex::Error` directly instead of `use hex::Error as HexError`.
