Sergio Benitez 4f3511786c Introduce statically-enforced 'Rocket' phasing.
The core 'Rocket' type is parameterized: 'Rocket<P: Phase>', where
'Phase' is a newly introduced, sealed marker trait. The trait is
implemented by three new marker types representing the three launch
phases: 'Build', 'Ignite', and 'Orbit'. Progression through these three
phases, in order, is enforced, as are the invariants guaranteed by each
phase. In particular, an instance of 'Rocket' is guaranteed to be in its
final configuration after the 'Build' phase and represent a running
local or public server in the 'Orbit' phase. The 'Ignite' phase serves
as an intermediate, enabling inspection of a finalized but stationary
instance. Transition between phases validates the invariants required
by the transition.

All APIs have been adjusted appropriately, requiring either an instance
of 'Rocket' in a particular phase ('Rocket<Build>', 'Rocket<Ignite>', or
'Rocket<Orbit>') or operating generically on a 'Rocket<P>'.
Documentation is also updated and substantially improved to mention
required and guaranteed invariants.

Additionally, this commit makes the following relevant changes:

  * 'Rocket::ignite()' is now a public interface.
  * 'Rocket::{build,custom}' methods can no longer panic.
  * 'Launch' fairings are now 'ignite' fairings.
  * 'Liftoff' fairings are always run, even in local mode.
  * All 'ignite' fairings run concurrently at ignition.
  * Launch logging occurs on launch, not any point prior.
  * Launch log messages have improved formatting.
  * A new launch error kind, 'Config', was added.
  * A 'fairing::Result' type alias was introduced.
  * 'Shutdown::shutdown()' is now 'Shutdown::notify()'.

Some internal changes were also introduced:

  * Fairing 'Info' name for 'Templates' is now 'Templating'.
  * Shutdown is implemented using 'tokio::sync::Notify'.
  * 'Client::debug()' is used nearly universally in tests.

Sergio Benitez fd8c9ce795 Use launch-inferred '_' in most example code. 2021-04-13 18:12:39 -07:00
Sergio Benitez ad36b769bc Rename 'rocket::ignite()' to 'rocket::build()'.
...because loading up a Rocket while it's ignited is a bad idea.

More seriously, because 'Rocket.ignite()' will become an "execute
everything up to here" method.

Sergio Benitez 50c9e88cf9 Completely revamp, redo examples.
The new examples directory...

  * Contains a `README.md` explaining each example.
  * Consolidates examples into more complete chunks.
  * Is just better.

Resolves #1447.

Sergio Benitez 63a14525d8 UTF-8 routes. Forms revamp. Temp files. Capped.
So. Many. Changes.

This is an insane commit: simultaneously one of the best (because of all
the wonderful improvements!) and one of the worst (because it is just
massive) in the project's history.

Routing:
  * All UTF-8 characters are accepted everywhere in route paths. (#998)
  * `path` is now `uri` in `route` attribute: `#[route(GET, path = "..")]`
    becomes `#[route(GET, uri = "..")]`.

Forms Revamp
  * All form related types now reside in a new `form` module.
  * Multipart forms are supported. (resolves #106)
  * Collections are supported in forms and queries. (resolves #205)
  * Nested structures in forms and queries are supported. (resolves #313)
  * Form fields can be ad-hoc validated with `#[field(validate = expr)]`.
  * `FromFormValue` is now `FromFormField`, blanket implements `FromForm`.
  * Form field values are always percent-decoded apriori.

Temporary Files
  * A new `TempFile` data and form guard allows streaming data directly to a
    file which can then be persisted.
  * A new `temp_dir` config parameter specifies where to store `TempFile`.
  * The limits `file` and `file/$ext`, where `$ext` is the file extension,
    determines the data limit for a `TempFile`.

Capped
  * A new `Capped` type is used to indicate when data has been truncated due to
    incoming data limits. It allows checking whether data is complete or
    truncated.
  * `DataStream` methods return `Capped` types.
  * `DataStream` API has been revamped to account for `Capped` types.
  * Several `Capped<T>` types implement `FromData`, `FromForm`.
  * HTTP 413 (Payload Too Large) errors are now returned when data limits are
    exceeded. (resolves #972)

Hierarchical Limits
  * Data limits are now hierarchical, delimited with `/`. A limit of `a/b/c`
    falls back to `a/b` then `a`.

Core
  * `&RawStr` no longer implements `FromParam`.
  * `&str` implements `FromParam`, `FromData`, `FromForm`.
  * `FromTransformedData` was removed.
  * `FromData` gained a lifetime for use with request-local data.
  * The default error HTML is more compact.
  * `&Config` is a request guard.
  * The `DataStream` interface was entirely revamped.
  * `State` is only exported via `rocket::State`.
  * A `request::local_cache!()` macro was added for storing values in
    request-local cache without consideration for type uniqueness by using a
    locally generated anonymous type.
  * `Request::get_param()` is now `Request::param()`.
  * `Request::get_segments()` is now `Request::segments()`, takes a range.
  * `Request::get_query_value()` is now `Request::query_value()`, can parse any
    `FromForm` including sequences.
  * `std::io::Error` implements `Responder` like `Debug<std::io::Error>`.
  * `(Status, R)` where `R: Responder` implements `Responder` by overriding the
    `Status` of `R`.
  * The name of a route is printed first during route matching.
  * `FlashMessage` now only has one lifetime generic.

HTTP
  * `RawStr` implements `serde::{Serialize, Deserialize}`.
  * `RawStr` implements _many_ more methods, in particular, those related to the
    `Pattern` API.
  * `RawStr::from_str()` is now `RawStr::new()`.
  * `RawStr::url_decode()` and `RawStr::url_decode_lossy()` only allocate as
    necessary, return `Cow`.
  * `Status` implements `Default` with `Status::Ok`.
  * `Status` implements `PartialEq`, `Eq`, `Hash`, `PartialOrd`, `Ord`.
  * Authority and origin part of `Absolute` can be modified with new
    `Absolute::{with,set}_authority()`, `Absolute::{with,set}_origin()` methods.
  * `Origin::segments()` was removed in favor of methods split into query and
    path parts and into raw and decoded versions.
  * The `Segments` iterator is smarter, returns decoded `&str` items.
  * `Segments::into_path_buf()` is now `Segments::to_path_buf()`.
  * A new `QuerySegments` is the analogous query segment iterator.
  * Once set, `expires` on private cookies is not overwritten. (resolves #1506)
  * `Origin::path()` and `Origin::query()` return `&RawStr`, not `&str`.

Codegen
  * Preserve more spans in `uri!` macro.
  * Preserve spans `FromForm` field types.
  * All dynamic parameters in a query string must typecheck as `FromForm`.
  * `FromFormValue` derive removed; `FromFormField` added.
  * The `form` `FromForm` and `FromFormField` field attribute is now named
    `field`. `#[form(field = ..)]` is now `#[field(name = ..)]`.

Contrib
  * `Json` implements `FromForm`.
  * `MsgPack` implements `FromForm`.
  * The `json!` macro is exported as `rocket_contrib::json::json!`.
  * Added clarifying docs to `StaticFiles`.

Examples
  * `form_validation` and `form_kitchen_sink` removed in favor of `forms`.
  * The `hello_world` example uses unicode in paths.
  * The `json` example only allocates as necessary.

Internal
  * Codegen uses new `exports` module with the following conventions:
    - Locals starts with `__` and are lowercased.
    - Rocket modules start with `_` and are lowercased.
    - `std` types start with `_` and are titlecased.
    - Rocket types are titlecased.
  * A `header` module was added to `http`, contains header types.
  * `SAFETY` is used as doc-string keyword for `unsafe` related comments.
  * The `Uri` parser no longer recognizes Rocket route URIs.

Sergio Benitez 092e03f720 Generate a proxy structure for better namespacing.
Prior to this commit, it was impossible to 'use' a route from a separate
namespace for use in a 'routes!' macro. Naturally, this was a common
source of confusion amongst users. This commit obviates this deficiency
by generating a "proxy" structure that can be imported and converted
into a 'Route'/'Catcher' or their static variants.

This change is largely backwards compatible but can break existing code
when routes are named identically to other types in the namespace.

Sergio Benitez 12308b403f Add '#[rocket::launch]' attribute.
The attribute is applied everywhere it can be across the codebase and is
the newly preferred method for launching an application. This commit

functions other than 'main'.

Sergio Benitez 95c981de79 Test all guide code examples.
Every code example is now fully runnable and testable. As a result, all
examples are now tested and include imports. Relevant imports are shown
by default. Code examples can be expanded to show all imports.

Fixes #432.
