No_std support
This library would be nice to see in no std environment, especially considering the global trend for moving rust libraries to no_std (bincode, smallvec, thiserror).
I managed to make this library work on bare metal, but i did it very quickly without considering all possible use cases, please see commit https://github.com/skibon02/garde-nostd/commit/6bf09e4da2242b6f73ced3e253ccebbc127e6cd3.
Some notes about this fork version:
- removed support HashSet and HashMap
- tests still require std support
- removed "std" feature from regex
As for further steps, we should introduce enabled by default feature "std" and feature-gate all std-specific functionality under this feature (which only covers HashSet and HashMap, and maybe some of other library features)
I can open PR and complete all the necessary changes for this library to work on both no_std and std
smallvec is currently in alpha, but I don't think there'll be much breaking changes until 2.0.0 release
Please note that I don't have much time to work on this library or review PRs right now. The changes seems reasonable. It would also be nice to have a fully zero-alloc mode (related to https://github.com/jprochazk/garde/issues/1), but that's out of scope for now.
