Make the library compile for no_std

Open tomaka opened this issue 5 years ago • 4 comments

Everything in the title.

For obvious reasons, only wasmi would be supported.

Summary after #116:

  • parity-multiaddr doesn't support no_std.
  • num-rational needs a bugfix for no_std to work.
  • slab needs a bugfix for no_std to work and is completely unmaintained. We probably need to publish a fork.
  • nom supports no_std in master but not in the crates.io version.
  • prost supports no_std in master but not in the crates.io version. However, some brief testing of the git version showed that it still tried to use std anyway.

I forgot snow, which doesn't support no_std either.

After #579, smoldot itself compiles for no_std, but not all of its dependencies. In order to consider this finished, a CI check should be added that compiles smoldot for a platform that doesn't have a std.

Still blocked on snow. At the moment, the compilation fails on subtle, but it's because its std feature is pulled by snow.
