Also updates 'tokio-rustls' to a compatible version.
Additionally depends on 'rustls-pemfile' which includes functionality
that was previously part of 'rustls' itself.
Instead of a constructor, 'MediaType::with_params()' and
'ContentType::with_params()' are now both builder methods. This allow
chaining the method to associated constants.
This has the following nice benefits:
* The 'Uuid' wrapper type is gone.
* 'Uuid' implements 'UriDisplay', 'FromUriParam'.
* The 'serialization' example merges in 'uuid'.
Resolves#1299.
The 'SpaceHelmet' fairing is now called 'Shield'. It features the
following changes and improvements:
* Headers which are now ignored by browsers are removed.
* 'XssFilter' is no longer an on-by-default policy.
* A new 'Permission' policy is introduced.
* 'Shield' is attached to all 'Rocket' instances by default.
* Default headers never allocate on 'Clone'.
* Policy headers are rendered once and cached at start-up.
* Improved use of typed URIs in policy types.
This commit entirely rewrites Rocket's URI parsing routines and
overhauls the 'uri!' macro resolving all known issues and removing any
potential limitations for compile-time URI creation. This commit:
* Introduces a new 'Reference' URI variant for URI-references.
* Modifies 'Redirect' to accept 'TryFrom<Reference>'.
* Introduces a new 'Asterisk' URI variant for parity.
* Allows creation of any URI type from a string literal via 'uri!'.
* Enables dynamic/static prefixing/suffixing of route URIs in 'uri!'.
* Unifies 'Segments' and 'QuerySegments' into one generic 'Segments'.
* Consolidates URI formatting types/traits into a 'uri::fmt' module.
* Makes APIs more symmetric across URI types.
It also includes the following less-relevant changes:
* Implements 'FromParam' for a single-segment 'PathBuf'.
* Adds 'FileName::is_safe()'.
* No longer reparses upstream request URIs.
Resolves#842.
Resolves#853.
Resolves#998.
The crux of the implementation is as follows:
* Configurable ctrl-c, signals that trigger a graceful shutdown.
* Configurable grace period before forced I/O termination.
* Programatic triggering via an application-wide method.
* A future (`Shutdown`) that resolves only when shutdown is requested.
Resolves#180.
Launch fairings are now fallible and take the place of attach fairings,
but they are only run, as the name implies, at launch time.
This is is a fundamental shift from eager execution of set-up routines,
including the now defunct attach fairings, to lazy execution,
precipitated by the transition to `async`. The previous functionality,
while simple, caused grave issues:
1. A instance of 'Rocket' with async attach fairings requires an async
runtime to be constructed.
2. The instance is accessible in non-async contexts.
3. The async attach fairings have no runtime in which to be run.
Here's an example:
```rust
let rocket = rocket::ignite()
.attach(AttachFairing::from(|rocket| async {
Ok(rocket.manage(load_from_network::<T>().await))
}));
let state = rocket.state::<T>();
```
This had no real meaning previously yet was accepted by running the
attach fairing future in an isolated runtime. In isolation, this causes
no issue, but when attach fairing futures share reactor state with other
futures in Rocket, panics ensue.
The new Rocket application lifecycle is this:
* Build - A Rocket instance is constructed. No fairings are run.
* Ignition - All launch fairings are run.
* Liftoff - If all launch fairings succeeded, the server is started.
New 'liftoff' fairings are run in this third phase.
Catchers can now be scoped to paths, with preference given to the
longest-prefix, then the status code. This a breaking change for all
applications that register catchers:
* `Rocket::register()` takes a base path to scope catchers under.
- The previous behavior is recovered with `::register("/", ...)`.
* Catchers now fallibly, instead of silently, collide.
* `ErrorKind::Collision` is now `ErrorKind::Collisions`.
Related changes:
* `Origin` implements `TryFrom<String>`, `TryFrom<&str>`.
* All URI variants implement `TryFrom<Uri>`.
* Added `Segments::prefix_of()`.
* `Rocket::mount()` takes a `TryInto<Origin<'_>>` instead of `&str`
for the base mount point.
* Extended `errors` example with scoped catchers.
* Added scoped sections to catchers guide.
Internal changes:
* Moved router code to `router/router.rs`.
The new benchmarks use routes from real-world project. This is much more
realistic than the previous benchmarks.
The new benchmarks use `criterion` and exist in their own Cargo project.
