We've adopted `tracing` for diagnostics, but currently, it is just being used as a drop-in replacement for the `log` crate. Ideally, we would want to start emitting more structured diagnostics, using `tracing`'s `Span`s and structured key-value fields. A lot of the logging in `h2` is already written in a style that imitates the formatting of structured key-value logs, but as textual log messages. Migrating the logs to structured `tracing` events therefore is pretty easy to do. I've also started adding spans, mostly in the read path. Finally, I've updated the tests to use `tracing` rather than `env_logger`. The tracing setup happens in a macro, so that a span for each test with the test's name can be generated and entered. This will make the test output easier to read if multiple tests are run concurrently with `--nocapture`. Signed-off-by: Eliza Weisman <eliza@buoyant.io>
H2
A Tokio aware, HTTP/2.0 client & server implementation for Rust.
More information about this crate can be found in the crate documentation.
Features
- Client and server HTTP/2.0 implementation.
- Implements the full HTTP/2.0 specification.
- Passes h2spec.
- Focus on performance and correctness.
- Built on Tokio.
Non goals
This crate is intended to only be an implementation of the HTTP/2.0 specification. It does not handle:
- Managing TCP connections
- HTTP 1.0 upgrade
- TLS
- Any feature not described by the HTTP/2.0 specification.
This crate is now used by hyper, which will provide all of these features.
Usage
To use h2, first add this to your Cargo.toml:
[dependencies]
h2 = "0.2"
Next, add this to your crate:
extern crate h2;
use h2::server::Connection;
fn main() {
// ...
}
FAQ
How does h2 compare to solicit or rust-http2?
The h2 library has implemented more of the details of the HTTP/2.0 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.
Is this an embedded Java SQL database engine?
No.
