We do this by shoving it into Rust. We believe our python http client is
a bit slow.
Also bumps minimum rust version to 1.81.0, released last September (over
six months ago)
To allow for async Rust, includes some adapters between Tokio in Rust
and the Twisted reactor in Python.
This adds functions to transform a Twisted request to the
`http::Request`, and then to send back an `http::Response` through it.
It also imports the SynapseError exception so that we can throw that
from Rust code directly
Example usage of this would be:
```rust
use crate::http::{http_request_from_twisted, http_response_to_twisted, HeaderMapPyExt};
fn handler(twisted_request: &PyAny) -> PyResult<()> {
let request = http_request_from_twisted(twisted_request)?;
let ua: headers::UserAgent = request.headers().typed_get_required()?;
if whatever {
return Err((crate::errors::SynapseError::new(
StatusCode::UNAUTHORIZED,
"Whatever".to_owned
"M_UNAUTHORIZED",
None,
None,
)));
}
let response = Response::new("hello".as_bytes());
http_response_to_twisted(twisted_request, response)?;
Ok(())
}
```
