Overhaul URI types. 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.

//! This crate contains officially sanctioned contributor libraries that provide
//! functionality commonly used by Rocket applications.
//!
//! These libraries are always kept in-sync with the core Rocket library. They
//! provide common, but not fundamental, abstractions to be used by Rocket
//! applications.
//!
//! Each module in this library is held behind a feature flag, with the most
//! common modules exposed by default. The present feature list is below, with
//! an asterisk next to the features that are enabled by default:
//!
2018-10-07 00:24:11 +00:00
//! * [json*](type@json) - JSON (de)serialization
//! * [serve*](serve) - Static File Serving
//! * [msgpack](msgpack) - MessagePack (de)serialization
//! * [handlebars_templates](templates) - Handlebars Templating
//! * [tera_templates](templates) - Tera Templating
//! * [uuid](uuid) - UUID (de)serialization
//! * [${database}_pool](databases) - Database Configuration and Pooling
//! * [helmet](helmet) - Fairing for Security and Privacy Headers
//!
//! The recommend way to include features from this crate via Cargo in your
//! project is by adding a `[dependencies.rocket_contrib]` section to your
//! `Cargo.toml` file, setting `default-features` to false, and specifying
//! features manually. For example, to use the JSON module, you would add:
//!
//! ```toml
//! [dependencies.rocket_contrib]
2018-10-31 20:29:22 +00:00
//! version = "0.4.0-rc.1"
//! default-features = false
//! features = ["json"]
//! ```
//!
//! This crate is expected to grow with time, bringing in outside crates to be
//! officially supported by Rocket.
