This commits also implement the query reform from #608. It also consists
of many, many breaking changes. Among them are:
* Query parts in route paths use new query reform syntax.
* Routing for queries is now lenient.
- Default ranking has changed to reflect query reform.
* Format routing matching has been fixed.
- Routes with formats matching "accept" will always collide.
- Routes with formats matching "content-type" require requests to
have an equivalent content-type header to match.
- Requests with imprecise content-types are treated as not having a
content-type.
* Generated routes and catchers respect visibility modifiers.
* Raw getter methods from request were renamed and retooled.
- In particular, the index parameter is based on segments in the
route path, not dynamic parameters.
* The method-based attributes no longer accept a keyed 'path'.
* The 'rocket_codegen' crate is gone and will no longer be public.
* The 'FormItems' iterator emits values of type 'FormItem'.
- The internal form items' string can no longer be retrieved.
* In general, routes are more strictly validated.
* Logging from codegen now funnels through logging infrastructure.
* Routing has been optimized by caching routing metadata.

The new 'FromData' trait allows an implementor to instruct the caller to
maintain state on its stack and later pass a borrow for processing.
Among other things, it greatly simplifies the 'Form' type, removing a
use of unsafe, and allows references in deserialized data guards.
This completes the migration of custom derives to proc-macros, removing
the need for the `custom_derive` feature in consumer code. This commit
also includes documentation, unit tests, and compile UI tests for each
of the derives.
Additionally, this commit improves the existing `FromForm` and
`FromFormValue` derives. The generated code for `FromForm` now returns
an error value indicating the error condition. The `FromFormValue`
derive now accepts a `form` attribute on variants for specifying the
exact value string to match against.
Closes#590.
Closes#670.
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.
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 is a (minor) breaking change. If `rocket.launch()` is the last expression
in a function, the return type will change from `()` to `LaunchError`. A simple
workaround that preserves the previous functionality is to simply add a
semicolon after `launch()`: `rocket.launch();`.
resolves#34
This commit includes the following additions:
* A `session` example was added.
* `Config::take_session_key` was removed.
* If a `session_key` is not supplied, one is automatically generated.
* The `Session` type implements signed, encrypted sessions.
* A `Session` can be retrieved via its request guard.
