**How does h2 compare to [solicit] or [rust-http2]?**
The h2 library has implemented more of the details of the HTTP/2 specification
than any other Rust library. It also passes the [h2spec] set of tests. The h2
library is rapidly approaching "production ready" quality.
Besides the above, Solicit is built on blocking I/O and does not appear to be
actively maintained.
