wasm support #18

Open asimpletune opened 1 year ago

asimpletune commented 1 year ago

Hello, thanks for taking time to make these great libraries. Is wasm support something that's possible?

I was able to use mail-parser in a wasm environment, but haven't had the same luck for mail-auth.

Thank you!

mdecimus commented 1 year ago

Hi, the default crypto backend of mail-auth uses the ring crate which might not compile to WASM as it includes some Assembler code. You can try disabling the default features and enabling the rust-crypto feature which uses a different library in pure Rust so you'll probably have better luck.

Ok, thank you for the suggestion. I will try it out.

Do you have any suggestions for 

error: failed to run custom build command for `zstd-sys v2.0.8+zstd.1.5.5`
asimpletune commented 1 year ago

Actually, the above error only happens intermittently, but that part succeeds most of them time. Where I get blocked, even with rust-crypto feature specified and default features turned off is a bunch of error messages mostly around sys.
