This commit includes the following important API changes:
* The `form` route parameter has been removed.
* The `data` route parameter has been added.
* Forms are not handled via the `data` parameter and `Form` type.
* Removed the `data` parameter from `Request`.
* Added `FromData` conversion trate and default implementation.
* Added `DataOutcome` enum, which is the return type of `from_data`.
* 'FromData' is now used to automatically derive the `data` parameter.
* Moved `form` into `request` module.
* Removed `Failure::new` in favor of direct value construction.
This commit includes the following important package additions:
* Added a 'raw_upload' example.
* `manual_routes` example uses `Data` parameter.
* Now building and running tests with `--all-features` flag.
* All exmaples have been updated to latest API.
* Now using upstream Tera.
This commit includes the following important fixes:
* Any valid ident is now allowed in single-parameter route parameters.
* Lifetimes are now properly stripped in code generation.
* `FromForm` derive now works on empty structs.
Summary of changes:
* Request no longer has a lifetime parameter.
* Handler type now includes a `Data` parameter.
* Response is now an enum that is either `Complete` or `Forward`.
* Outcome enum is now one of: Success, Failure, Forward.
* Outcome::Foward for Responses must include StatusCode.
* Responders are now final: they cannot forward to requests. (!!)
* Responsers may only forward to catchers. (!!)
* Response no longer provides wrapping methods.
* Route is now cloneable.
This change is fundamental to enabling streaming requests.
* Add content-type responsers for JSON, HTML, and plain text.
* Use content-type responders in content_type example.
* Conditionally create Request `from` HypRequest.
* Clean-up dispatching and handling in main rocket.
* Change Level enum to Logging Level and reexport.
* Allow users to set logging level before launch.
* Fix content_type example error handling.
* Percent decode params when user requests `String`.
The error function now takes in a "RoutingError" structure. The idea is that the
structure includes all of the information necessary for a user to processor the
error as they wish. This interface is very incomplete and may change. At a
minimum, the error structure should include:
1) The request that failed.
2) Why the request failed.
3) The chain of attempted route matches, if any.
4) Something else?
This means we have almost all of the infrastructure in place to properly use
ranked requests. At the moment, we only use this to allow user error handlers
when a responder fails. But, soon enough, we'll try the next highest ranked
route until there are no more matching routes. Yipee!
A few important things needs to get this to be 'right':
1a. Have a way to return a response with a status code.
1b. Use that mechanism in the default catchers.
2. Automatically fill in that code from the #[error] handler.
3. Have a way for a responder to say if responding succeeded.
4. Try next highest ranking route if responding with one handler fails.
Added `error` decorator and `errors` macro.
The current idea is that you can have "catchers" for all valid errors code (in
range [400, 500). At the moment, catchers are just request handlers, and the
decorator expected an empty function signature for the error handler. Obviously,
this is pretty useless. Not sure on what the API should be here. But, progress.
Oh, one more thing: who should handle forwarding a request to a catcher?
Probably not the router. So, the main Rocket should?
Here's the idea: under the `Rocket` namespace should live things critical to
writing simple Rocket apps: Request, Response, Error, etc. Nothing should be
nested more than one level deep. Only items required for more complex things
(implementing uncommon traits, etc.) should be nested one level deep.
This commit is the first attempt at realizing this.
