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. Resolves #2671. Resolves #1070. |

Rocket Examples
This directory contains projects showcasing Rocket's features.
Applications
-
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. -
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.
-
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 RocketFigment
, how to store and retrieve an application specific configuration in managed state usingAdHoc::config()
, and how to set configuration values inRocket.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 ofsqlx
,diesel
, andrusqlite
. Runs migrations automatically for the former two drivers. Usescontrib
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 customCounter
fairing and usingAdHoc
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 likeunsafe
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, andEither
. In the process, showcases usingTempFile
for raw uploads. Also illustrates the creation of a custom, derivedResponder
. -
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
- UsesFileServer
to serve static files. Also creates asecond
manual yet safe version. -
templating
- Illustrates usingcontrib
templates
support with identical examples for handlebars and tera. -
testing
- Uses Rocket'slocal
libraries to test an application. Showcases necessary use of theasync
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.
