no_std support

[ft-filancore]

Thank you very much for maintaining this crate. We'd love to use this in no_std environments (but with alloc support). Would it be feasible to add no_std support to this implementation?

[evik42]

I will look into it, with alloc support it could work as that would allow serde_json.

@ft-filancore I looked into this and unfortunately serde_json does not expose the Serializer and Formatter traits in a no_std build. I was looking into how to solve it, but it looks like I would need to rewrite the whole library to use a different approach.

I will keep this open and probably take a stab at it when I have more time, I am not sure when that happens.

@evik42 Could you confirm that this library would be compatible with the changes made in this PR? serde-rs/json#1280

As the author of said PR, I think this library would probably need the mechanical changes from io::Write to ser::Write, fromwrite_all with &[u8] as input to write_string with &str as input, and then will need to handle escape characters in some way compatible with whatever I end up doing. The changes are easy to do, so I'll be happy to do them assuming I get serde-rs/json#1280 merged, but ping me if I forget.
