Sergio Benitez fd294049c7 Update to hyper 1. Enable custom + unix listeners.
This commit completely rewrites Rocket's HTTP serving. In addition to
significant internal cleanup, this commit introduces the following major
features:

  * Support for custom, external listeners in the `listener` module.

    The new `listener` module contains new `Bindable`, `Listener`, and
    `Connection` traits which enable composable, external
    implementations of connection listeners. Rocket can launch on any
    `Listener`, or anything that can be used to create a listener
    (`Bindable`), via a new `launch_on()` method.

  * Support for Unix domain socket listeners out of the box.

    The default listener backwards compatibly supports listening on Unix
    domain sockets. To do so, configure an `address` of
    `unix:path/to/socket` and optional set `reuse` to `true` (the
    default) or `false` which controls whether Rocket will handle
    creating and deleting the unix domain socket.

In addition to these new features, this commit makes the following major
improvements:

  * Rocket now depends on hyper 1.

  * Rocket no longer depends on hyper to handle connections. This allows
    us to handle more connection failure conditions which results in an
    overall more robust server with fewer dependencies.

  * Logic to work around hyper's inability to reference incoming request
    data in the response results in a 15% performance improvement.

  * `Client`s can be marked secure with `Client::{un}tracked_secure()`,
    allowing Rocket to treat local connections as running under TLS.

  * The `macros` feature of `tokio` is no longer used by Rocket itself.
    Dependencies can take advantage of this reduction in compile-time
    cost by disabling the new default feature `tokio-macros`.

  * A new `TlsConfig::validate()` method allows checking a TLS config.

  * New `TlsConfig::{certs,key}_reader()`,
    `MtlsConfig::ca_certs_reader()` methods return `BufReader`s, which
    allow reading the configured certs and key directly.

  * A new `NamedFile::open_with()` constructor allows specifying
    `OpenOptions`.

These improvements resulted in the following breaking changes:

  * The MSRV is now 1.74.
  * `hyper` is no longer exported from `rocket::http`.
  * `IoHandler::io` takes `Box<Self>` instead of `Pin<Box<Self>>`.
    - Use `Box::into_pin(self)` to recover the previous type.
  * `Response::upgrade()` now returns an `&mut dyn IoHandler`, not
    `Pin<& mut _>`.
  * `Config::{address,port,tls,mtls}` methods have been removed.
    - Use methods on `Rocket::endpoint()` instead.
  * `TlsConfig` was moved to `tls::TlsConfig`.
  * `MutualTls` was renamed and moved to `mtls::MtlsConfig`.
  * `ErrorKind::TlsBind` was removed.
  * The second field of `ErrorKind::Shutdown` was removed.
  * `{Local}Request::{set_}remote()` methods take/return an `Endpoint`.
  * `Client::new()` was removed; it was previously deprecated.

Internally, the following major changes were made:

  * A new `async_bound` attribute macro was introduced to allow setting
    bounds on futures returned by `async fn`s in traits while
    maintaining good docs.

  * All utility functionality was moved to a new `util` module.

Rocket Examples

This directory contains projects showcasing Rocket's features.

Applications

  • pastebin

    A simple, API-only pastebin application, similar to https://paste.rs. Stores pastes locally on the file system. Implements a custom parameter guard, PasteId, to parse and validate paste identifiers.

  • todo

    A todo app with a web UI to add, delete, and mark/unmark items. Uses a SQLite database driven by diesel. Runs migrations automatically at start-up. Uses tera to render templates.

  • chat

    A real-time, multi-room chat application using Server-Sent Events (SSE) and JavaScript's EventSource. Supports automatic reconnection with exponential backoff and live connection status.

Feature Examples

  • config - Illustrates how to extract values from a Rocket Figment, how to store and retrieve an application specific configuration in managed state using AdHoc::config(), and how to set configuration values in Rocket.toml.

  • cookies - Uses cookies to create a client-side message box. Uses private cookies for a session-based authentication.

  • databases - Implements a CRUD-like "blog" JSON API backed by a SQLite database driven by each of sqlx, diesel, and rusqlite. Runs migrations automatically for the former two drivers. Uses contrib database support for all drivers (rocket_db_pools for the first; rocket_sync_db_pools for the other latter two).

  • error-handling - Exhibits the use of scoped catchers; contains commented out lines that will cause a launch-time error with code to custom-display the error.

  • fairings - Exemplifies creating a custom Counter fairing and using AdHoc fairings.

  • forms - Showcases all of Rocket's form support features including multipart file uploads, ad-hoc validations, field renaming, and use of form context for staged forms.

  • hello - Basic example of Rocket's core features: route declaration with path and query parameters, both simple and compound, mounting, launching, testing, and returning simple responses. Also showcases using UTF-8 in route declarations and responses.

  • manual-routing - An example eschewing Rocket's codegen in favor of manual routing. This should be seen as last-ditch effort, much like unsafe in Rust, as manual routing also eschews many of Rocket's automatic web security guarantees.

  • responders - Illustrates the use of many of Rocket's built-in responders: Stream, Redirect, File, NamedFile, content for manually setting Content-Types, and Either. In the process, showcases using TempFile for raw uploads. Also illustrates the creation of a custom, derived Responder.

  • serialization - Showcases JSON and MessagePack (de)serialization support by implementing a CRUD-like message API in JSON and a simply read/echo API in MessagePack. Showcases UUID parsing support.

  • state - Illustrates the use of request-local state and managed state. Uses request-local state to cache "expensive" per-request operations. Uses managed state to implement a simple index hit counter. Also uses managed state to store, retrieve, and push/pop from a concurrent queue.

  • static-files - Uses FileServer to serve static files. Also creates a second manual yet safe version.

  • templating - Illustrates using contrib templates support with identical examples for handlebars and tera.

  • testing - Uses Rocket's local libraries to test an application. Showcases necessary use of the async Client. Note that all examples contains tests, themselves serving as examples for how to test Rocket applications.

  • tls - Illustrates configuring TLS with a variety of key pair kinds.

  • upgrade - Uses the connection upgrade API to implement WebSocket support using tungstenite.
