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.

Rocket Todo Example
This example makes use of a SQLite database via diesel to store todo tasks. As
a result, you'll need to have sqlite3 and its headers installed:
- OS X:
brew install sqlite - Debian/Ubuntu:
apt-get install libsqlite3-dev - Arch:
pacman -S sqlite
Running
Before running, building, or testing this example, you'll need to ensure the following:
- A SQLite database file with the proper schema is present.
On a Unix machine or with bash installed, you can simply run the
`boostrap.sh` script to create the database. The script installs the
`diesel_cli` tools if they're not already installed and runs the migrations.
The script will output a `DATABASE_URL` variable.
You can also run the migrations manually with the following commands:
```
cargo install diesel_cli # install diesel CLI tools
DATABASE_URL=db/db.sql diesel migration run # create db/db.sql
```
-
A
DATABASE_URLenvironment variable is set that points to the SQLite database file.Use the
DATABASE_URLvariable emitted from thebootstrap.shscript, or enter it manually, as follows:DATABASE_URL=db/db.sql cargo buildDATABASE_URL=db/db.sql cargo testDATABASE_URL=db/db.sql cargo run
