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.
The user-facing changes effected by this commit are:
* The 'http::Cookies<'_>' guard is now '&http::CookieJar<'_>'.
* The "one-at-a-time" jar restriction is no longer imposed.
* 'CookieJar' retrieval methods return 'http::CookieCrumb'.
* The 'private-cookies' feature is now called 'secrets'.
* Docs flag private cookie methods with feature cfg.
* Local, async request dispatching is never serialized.
* 'Client::cookies()' returns the tracked 'CookieJar'.
* 'LocalResponse::cookies()' returns a 'CookieJar'.
* 'Response::cookies()' returns an 'impl Iterator'.
* A path of '/' is set by default on all cookies.
* 'SameSite=strict' is set by default on all cookies.
* 'LocalRequest::cookies()' accepts any 'Cookie' iterator.
* The 'Debug' impl for 'Request' prints the cookie jar.
Resolves#1332.
The bulk of the changes in this commit are for creating an
'ErrorHandler' trait that works like the 'Handler' trait, but for
errors. Furthermore, Rocket's default catcher now responds with a JSON
payload if the preferred 'Accept' media type is JSON.
This commit also fixes a bug in 'LocalRequest' where the internal
'Request' contained an correct 'URI'.
This commit aims to make it impossible to modify a 'Route' structure in
a way that violates expectations of a code-generated 'Route'. It removes
'Route::set_uri()' in favor of 'Route::map_base()', which allows for
safe modifications of the route's base.
In a similar vain, this commit also includes the following changes:
* 'Route::path()' was added to safely retrieve the route's 'path'.
* The base of a 'Route' is underlined during launch printing.
* 'Origin::into_normalized()' replaces 'Origin::to_normalized()'.
Fixes#1262.
This removes the 'ctrl_c_shutdown' feature opting instead for a 'ctrlc'
configuration option. To avoid further merge conflicts with the master
branch, the option is currently read as an extra.

Also:
* Remove 'response::ResultFuture'.
* Re-export 'tokio' and 'futures' from the crate root.
* Make 'ResponseBuilder::sized_body()' and 'async fn'.
* Remove the 'Future' implementation for 'ResponseBuilder'.
* Add 'ResponseBuilder::finalize()' for finalizing the builder.
In order to avoid making 'ResponseBuilder::sized_body' an asynchronous
function, the seeking is deferred until finalization. 'finalize()' is
replaced with '.await', and 'ResponseBuilder::ok()' is an 'async fn'.
* Update 'tokio', 'tokio-rustls', and 'hyper'.
* Remove unused dependencies on some `futures-*` crates.
* Rework 'spawn_on', which is now 'serve'.
* Simplify Ctrl-C handling.
Use I/O traits and types from 'tokio-io' as much as possible.
A few adapters only exist in futures-io-preview and use
futures-tokio-compat as a bridge for now.
Types can now implement the new 'Listener' trait, which means they can
report the address they are listening on and asynchronously accept
connections. 'Connection's are read/write streams that can additionally
report the remote address.
Listener is implemented for 'tokio_net::tcp::TcpListener' and for
the new 'rocket_http::tls::TlsListener' based on 'tokio-rustls'.
The new private function 'Rocket::listen_on()' now does the main setup
for launch and is generic over a Listener. In the future, a more refined
version of the API can be exposed so that applications can implement
their own listeners.
This commit introduces the sealed `UriPart` marker trait as well as the
implementing `Path` and `Query` marker types, allowing for parts of a
URI to be distinguished at the type level. Consequently, `UriDisplay`
has been parameterized with `P: UriPart`, creating `UriDisplay<Path>`
and `UriDisplay<Query>`. The effect of this change is improved type
safely for URI rendering as well as the ability to omit rendering values
in query parts via `Option` and `Result`.
The `UriDisplay` derive was replaced by `UriDisplayQuery` and
`UriDisplayPath` which derive implementations for `UriDisplay<Path>`
and `UriDisplay<Query>`, respectively.
This commit also works around a rustdoc visibility issue by creating a
hidden `http::private` module.
Finally, this commit also removes the now vestigial use of the
`rustc_private` feature in codegen.
Fixes#827.
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.

This is fairly large commit with several entangled logical changes.
The primary change in this commit is to completely overhaul how URI
handling in Rocket works. Prior to this commit, the `Uri` type acted as
an origin API. Its parser was minimal and lenient, allowing URIs that
were invalid according to RFC 7230. By contrast, the new `Uri` type
brings with it a strict RFC 7230 compliant parser. The `Uri` type now
represents any kind of valid URI, not simply `Origin` types. Three new
URI types were introduced:
* `Origin` - represents valid origin URIs
* `Absolute` - represents valid absolute URIs
* `Authority` - represents valid authority URIs
The `Origin` type replaces `Uri` in many cases:
* As fields and method inputs of `Route`
* The `&Uri` request guard is now `&Origin`
* The `uri!` macro produces an `Origin` instead of a `Uri`
The strict nature of URI parsing cascaded into the following changes:
* Several `Route` methods now `panic!` on invalid URIs
* The `Rocket::mount()` method is (correctly) stricter with URIs
* The `Redirect` constructors take a `TryInto<Uri>` type
* Dispatching of a `LocalRequest` correctly validates URIs
Overall, URIs are now properly and uniformly handled throughout Rocket's
codebase, resulting in a more reliable and correct system.
In addition to these URI changes, the following changes are also part of
this commit:
* The `LocalRequest::cloned_dispatch()` method was removed in favor of
chaining `.clone().dispatch()`.
* The entire Rocket codebase uses `crate` instead of `pub(crate)` as a
visibility modifier.
* Rocket uses the `crate_visibility_modifier` and `try_from` features.
A note on unsafety: this commit introduces many uses of `unsafe` in the
URI parser. All of these uses are a result of unsafely transforming byte
slices (`&[u8]` or similar) into strings (`&str`). The parser ensures
that these casts are safe, but of course, we must label their use
`unsafe`. The parser was written to be as generic and efficient as
possible and thus can parse directly from byte sources. Rocket, however,
does not make use of this fact and so would be able to remove all uses
of `unsafe` by parsing from an existing `&str`. This should be
considered in the future.
Fixes#443.
Resolves#263.
All uses of `unsafe` are now thoroughly documented with arguments and
informal proofs of correctness as well as conditions that must hold for
these arguments to pass.
This commit also reduces the number of `unsafe` uses by 7, bringing the
count to ~10 non-test uses of `unsafe`.
