serde-saphyr replaces unsafe_libyaml

[bourumir-wyngs]

serde-saphyr is YAML serde implementation where we finally get rid of unsafe-libyaml (and its varieties like libyaml-safer ) with that was initially present in all clones of the former serde-yaml, now unmaintained. There goes my serde-yaml-bw, but also serde-yaml-ng , serde-norway, serde-yml, etc. Serde-saphyr finally replaces that library by the saphyr-parser.

While external crate, unsafe-libyaml quite often resulted in unsafe keyword being required in dependent create as well. At least I was not able to get rid of it regardless that I tried. serde-saphyr itself is unsafe-free, this has been verified also with geiger, #![forbid(unsafe_code)] present on the top of lib.rs so I am adding your badge to it. If somebody else would like to check this additionally, happy to get feedback.

That's excellent! I'm very happy to see a safe YAML implementation in Rust!

I'm going to go ahead and mark this completed.

It would be nice to add it to the RustSec advisory about serde-yaml if one exists; I see there's an outstanding PR for it: rustsec/advisory-db#2459
