Previously, the `NotFound` status code was used to signal many kinds of
recoverable, forwarding errors. This included validation errors, incorrect
Content-Type errors, and more.
This commit modifies the status code used to forward in these instances to more
precisely indicate the forwarding condition. In particular:
* Parameter `FromParam` errors now forward as 422 (`UnprocessableEntity`).
* Query paramater errors now forward as 422 (`UnprocessableEntity`).
* Use of incorrect form content-type forwards as 413 (`UnsupportedMediaType`).
* `WebSocket` guard now forwards as 400 (`BadRequest`).
* `&Host`, `&Accept`, `&ContentType`, `IpAddr`, and `SocketAddr` all forward
with a 500 (`InternalServerError`).
Additionally, the `IntoOutcome` trait was overhauled to support functionality
previously offered by methods on `Outcome`. The `Outcome::forward()` method now
requires a status code to use for the forwarding outcome.
Finally, logging of `Outcome`s now includes the relevant status code.
Resolves #2626.

sync_db_pools 
This crate provides traits, utilities, and a procedural macro for configuring
and accessing database connection pools in Rocket. This implementation is backed
by r2d2 and exposes connections through request guards.
Usage
First, enable the feature corresponding to your database type:
[dependencies.rocket_sync_db_pools]
version = "=0.1.0-rc.3"
features = ["diesel_sqlite_pool"]
A full list of supported databases and their associated feature names is
available in the crate docs. In whichever configuration source you choose,
configure a databases dictionary with a key for each database, here
sqlite_logs in a TOML source:
[default.databases]
sqlite_logs = { url = "/path/to/database.sqlite" }
In your application's source code:
#[macro_use] extern crate rocket;
use rocket_sync_db_pools::{database, diesel};
#[database("sqlite_logs")]
struct LogsDbConn(diesel::SqliteConnection);
#[get("/logs/<id>")]
async fn get_logs(conn: LogsDbConn, id: usize) -> Result<Logs> {
conn.run(|c| Logs::by_id(c, id)).await
}
#[launch]
fn rocket() -> _ {
rocket::build().attach(LogsDbConn::fairing())
}
See the crate docs for full details.
