This commit involves several breaking changes:
* `session_key` config param must be a 256-bit base64 encoded string.
* `FromRequest` is implemented for `Cookies`, not `Cookie`.
* Only a single `Cookies` instance can be retrieved at a time.
* `Config::take_session_key` returns a `Vec<u8>`.
* `Into<Header>` is implemented for `&Cookie`, not `Cookie`.
A few interesting notes on this breakage:
* `Cookie` how has a lifetime. It should be `'static'` everywhere.
* The `SetCookie` header is no longer reexported.
* Instead, `Cookie` implements `Into<Header>` for Set-Cookie.
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.
