Support for no_std environment?

[TheSamabo]

Hi,
i've been looking over some solutions to compression on embedded rust eg: no_std environment.

Does this crate require standard library?

Thanks, Sam

[main--]

The crate currently uses Vec<u8> in multiple places, so making it compatible with no_std would require some work. That being said, I would of course be open to reviewing and merging a PR adding no_std support (provided that it doesn't degrade performance).
