Return $messages instead of array() when rustfmt made no changes to the code

Fix comments in .rustfmt.toml, don't group rules but sort by alphabet. Use rustfmt +abc-nightly in the linter.

Use nightly rustfmt, which simplifies the linter substantially

Use cargo fmt -- --check to lint files, which outputs a diff, and process that.

something bizzare happened with my git, adding missing files

• Removed ALGO_NAME associated const
• Added copyright
• Fixed + tested Debug impl

• Check for minimum Rust version
• Simplify CMake following Fabiens diff

Resolve issues raised:

There are several copyright headers missing.

tar xzf (mandatory xkcd https://xkcd.com/1168/)

Install specific Rust version via rustup

In this case, it can be handled client-side. A library can provide a wrapper around chronik-client to accept addresses.

hash160 instead of addresses -- this complication should be handled server side, not app side. chronik should accept ecash addresses.

Add CheckArithmeticResult to intmat_tests for less copy-pasta

Verify [Add|Sub]Int63OverflowEmulated and [Add|Sub]Int63Overflow overflow for the same operands and produce the same result for for non-overflowing operands.

Actually fix the typo in "unreachable" in OP_CHECKMULTISIG

Add comment for the int64_t == long long int assertion.

Update detection of built-ins.

Fix spelling of available.

Use loop in GenInt63 instead of recursion

Re-run tests

Use assignment operator for bitshift in GenInt63

Fixed GenInt63 out of bounds case

Simplified GenInt63 using apparently non-UB

Improve GenInt63, generates random positive uniform 63-bit number first, then maps to random uniform bit-length and then negates with 50% chance.

Inlined and removed intmath.cpp and intmath_util.h. Renamed functions in intmath.h. Fixed copyright notice. Simplified conditional code.

Replaced by D9848

Add multiprecision/cpp_int.hpp Boost dependency (Lord have mercy)

Fix off-by-one error in overflow_add_int64 and overflow_sub_int64 (doesn't seem to appear on Darwin/clang)

Rebased from master

Merged FormatUserAgent and FormatSubVersionUserAgent

Updated commit message

Changed to -uaclientname and -uaclientversion as discussed.

Changed FormatSubVersion to FormatUserAgent and solely use FormatSubVersionUserAgent now

Changed to -uaclient, which sets the client name and version of the user agent, staying compatible with -uacomment

So what should I do instead

ok ok i admit this is cleaner now :rolling_eyes:

I'm not sure if this is what you want but it does look cleaner now, so maybe.

Made the test less functional and more loopy.

Refactored test cases

Actually use exhaustive test cases in curated flags case
