The 'try' impl for 'Outcome' allows the '?' operator to be used with
'Outcome' values. This is likely to make 'FromRequest' and 'FromData'
implementations more ergonomic.
This commit also expands the 'IntoOutcome' trait. It is now
implemented for 'Option'. It also now includes an additional
'or_forward' method.
This commit also changes the signature of the 'ContentType'
'from_extension" method so that it returns an 'Option<ContentType>' as
opposed to 'ContentType'.
This commit also disallows negative quality values in 'Accept' media
types.
This commit changes the 'FromForm' trait in two ways:
1. The singular method is now named 'from_form'.
2. The method takes a second parameter: 'strict: bool'.
The 'strict' parameter is used to specify whether form parsing should
be strict or not (i.e. lenient). When parsing is lenient, extra form
fields do not result in an error. This lenient behavior is used by a
new 'LenientForm' data guard type to request lenient form parsing. The
behavior for 'Form' remains unchanged.
Resolves#242.
Sessions
--------
This commit removes the `Session` type in favor of methods on the
`Cookies` types that allow for adding, removing, and getting private
(signed and encrypted) cookies. These methods provide a superset of
the functionality of `Session` while also being a minimal addition to
the existing API. They can be used to implement the previous `Session`
type as well as other forms of session storage. The new methods are:
* Cookie::add_private(&mut self, Cookie)
* Cookie::remove_private(&mut self, Cookie)
* Cookie::get_private(&self, &str)
Resolves#20
Testing
-------
This commit removes the `rocket::testing` module. It adds the
`rocket::local` module which provides a `Client` type for local
dispatching of requests against a `Rocket` instance. This `local`
package subsumes the previous `testing` package.
Rocket Examples
---------------
The `forms`, `optional_result`, and `hello_alt_methods` examples have
been removed. The following example have been renamed:
* extended_validation -> form_validation
* hello_ranks -> ranking
* from_request -> request_guard
* hello_tls -> tls
Other Changes
-------------
This commit also includes the following smaller changes:
* Config::{development, staging, production} constructors have been
added for easier creation of default `Config` structures.
* The `Config` type is exported from the root.
* `Request` implements `Clone` and `Debug`.
* `Request::new` is no longer exported.
* A `Response::body_bytes` method was added to easily retrieve a
response's body as a `Vec<u8>`.
This commit also adds the `base` field to `Route` which allows the
base mount point to be retrieved. Finally, this commits adds an
implementation of `FromRequest` for `Route` which returns the active
route if one is available or forwards otherwise.
This commit is a breaking change: it makes `Request` and `MockRequest`
invariant over the lifetime `'r`. While this shouldn't affect most
applications, it may affect some.
Resolves#108.
Differential and causal profiling determined that 35% of `Hello, world!`
dispatch time was spent rendering `Content-Type` due to many calls to `fmt` in
`MediaType::Display` and an allocation in `ContentType::Into<Header>`. This
change reduces the number of calls to `fmt` to 1 in `MediaType::Display` and
removes the allocation in `Into<Header>` for known media types.
This change also caches a `Rocket` "precheck" so that pre-dispatch checks are
done only a single time for a given `Rocket` instance, further reducing
`MockRequest::dispatch_with` time for "Hello, world!" by roughly 15%.
This commit includes two major changes to core:
1. Configuration state is no longer global. The `config::active()`
function has been removed. The active configuration can be
retrieved via the `config` method on a `Rocket` instance.
2. The `Responder` trait has changed. `Responder::respond(self)` has
been removed in favor of `Responder::respond_to(self, &Request)`.
This allows responders to dynamically adjust their response based
on the incoming request.
Additionally, it includes the following changes to core and codegen:
* The `Request::guard` method was added to allow for simple
retrivial of request guards.
* The `Request::limits` method was added to retrieve configured
limits.
* The `File` `Responder` implementation now uses a fixed size body
instead of a chunked body.
* The `Outcome::of<R: Responder>(R)` method was removed while
`Outcome::from<R: Responder(&Request, R)` was added.
* The unmounted and unmanaged limits are more cautious: they will only
emit warnings when the `Rocket` receiver is known.
This commit includes one major change to contrib:
1. To use contrib's templating, the fairing returned by
`Template::fairing()` must be attached to the running Rocket
instance.
Additionally, the `Display` implementation of `Template` was removed. To
directly render a template to a `String`, the new `Template::show`
method can be used.
Modifying the `Rocket` structure just before launch doesn't make sense for
several reasons: 1) those affects can't influence the launch, and 2) they won't
be observed in tests. Thus, an `Attach` fairing kind was added that ameliorates
these issues.
