Create a directory `bitcoin` and move into it the following as is with
no code changes:
- src
- Cargo.toml
- contrib
- test_data
- examples
Then do:
- Add a workspace to the repository root directory.
- Add the newly created `bitcoin` crate to the workspace.
- Exclude `fuzz` and `embedded` crates from the workspace.
- Add a contrib/test.sh script that runs contrib/test.sh in each
sub-crate
- Fix the bitcoin/contrib/test.sh script
For internal macros used only in this crate we do not need to use
`macro_use` and pollute the top level namespace now that we have edition
2018. We can add a `pub(crate) use` statement to each and then path
imports work for the macros like normal types.
73bc2bb058 Remove leading colons from ::core::cmp::Ordering (Tobin C. Harding)
bffe0e840d Remove _most_ leading double colons (Tobin C. Harding)
Pull request description:
Leading double colons are a relic of edition 2015. Attempt to remove _all_ leading double colons (assuming I didn't miss any).
- Patch 1 is done mechanically so it can be repeated by reviewers, just search-and-replace ' ::' with '::' (note the leading space).
- Patch 2 does a single other instance of leading `::`

Leading double colons are a relic of edition 2015. Remove all leading
double colons that follow a space, done like this so that reviewers can
do the same and verify the diff. Done with
search-and-replace ' ::' '::'
And, for the record:
```bash
function search-and-replace() {
if (($# != 2))
then
echo "Usage: $0 <this> <that>"
return
fi
local this="$1"
local that="$2"
for file in $(git grep -l "$this")
do
perl -pi -e "s/$this/$that/g" "$file"
done
}
```
When `rust-bitcoin` was started in 2014 the SPDX license list and short
identifiers where not a thing. Now that we have short identifiers and
they are gaining popularity in other projects we can consider using
them.
- Add links to the SPDX website in the readme
- Shorten the author section to a single line
- Remove all the licence information in each file and replace it with an
SPDX ID (see https://spdx.dev/ids/#how)
Of note:
- If the author of a file is explicitly listed, maintain this
information
- If the 'author' is listed as the generic 'Rust Bitcoin developers'
just remove the attribution, this is implicit. This does loose the date
info but that can be seen at any time from the git index using
`git log --follow --format=%ad --date default <FILE> | tail -1`
Add a macro `const_assert` that uses some const declaration trickery to
trigger a compile time error if a boolean expression is false.
Replace runtime checks using `debug_assert_eq!` with the newly defined
`const_assert!` macro.
Taking an external dependency just to convert ints to byte arrays
is somewhat of a waste, especially when Rust isn't very aggressive
about doing cross-crate LTO.
Note that the latest LLVM pattern-matches this, and while I haven't
tested it, that should mean this means no loss of optimization.
