It's different from #46 because MSRV with std is still 1.29, while for no_std the MSRV is 1.36 because it uses alloc.

Includes a test in CI building a no_std embedded program (the test requires nightly because of the allocator used). The embedded test is not run (only built) because there are issues with emulating arm on github action env.

@RCasatta RCasatta force-pushed the no-std branch 2 times, most recently from ecc59f2 to 3396f53 Compare April 13, 2021 13:51

The last force-push reduced the files needed for the embedded CI test as suggested in rust-bitcoin/bitcoin_hashes#120 (comment)

ACK

Tested as part of my upcoming no_std PR for rust-bitcoin on both 1.29 and stable.

Hi devrandom, there is a relevant discussion on rust-bitcoin/bitcoin_hashes#120 about how to implement no_std on rust-bitcoin, in particular for handling io::Read and io::Write. I am working on the PR on bitcoin_hashes

Thank you for pushing no_std forward, I hope we'll be able to build HW wallets one day using rust-bitcoin 😃
