#![doc(html_root_url = "https://docs.rs/webdav-handler/0.2.0-alpha.1")]
//! ## Generic async HTTP/WEBDAV handler
//!
//! [`Webdav`] ([RFC4918]) is HTTP (GET/HEAD/PUT/DELETE) plus a bunch of extra methods.
//!
//! This crate implements a futures/stream based webdav handler for Rust, using
//! the types from the `http` crate. It comes complete with an async filesystem
//! backend, so it can be used as a WEBDAV filesystem server, or just as a
//! feature-complete HTTP server.
//!
//! ## Interface.
//!
//! It has an interface similar to the Go x/net/webdav package:
//!
//! - the library contains an [HTTP handler][DavHandler]
//! - you supply a [filesystem][DavFileSystem] for backend storage, which can optionally
//!   implement reading/writing [DAV properties][DavProp].
//! - you can supply a [locksystem][DavLockSystem] that handles the webdav locks
//!
//! With some glue code, this handler can be used from HTTP server
//! libraries/frameworks such as [hyper].
//! (See [examples/hyper.rs][hyper_example]).
//!
//! ## Implemented standards.
//!
//! Currently [passes the "basic", "copymove", "props", "locks" and "http"
//! checks][README_litmus] of the Webdav Litmus Test testsuite. That's all of the base
//! [RFC4918] webdav specification.
//!
//! The litmus test suite also has tests for RFC3744 "acl" and "principal",
//! RFC5842 "bind", and RFC3253 "versioning". Those we do not support right now.
//!
//! The relevant parts of the HTTP RFCs are also implemented, such as the
//! preconditions (If-Match, If-None-Match, If-Modified-Since, If-Unmodified-Since,
//! If-Range), partial transfers (Range).
//!
//! Also implemented is `partial PUT`, for which there are currently [two
//! non-standard ways][PartialPut] to do it: [`PUT` with the `Content-Range` header][PUT],
//! which is what Apache's `mod_dav` implements, and [`PATCH` with the `X-Update-Range`
//! header][PATCH] from `SabreDav`.
//!
//! ## Backends.
//!
//! Included are two filesystems:
//!
//! - [`LocalFs`]: serves a directory on the local filesystem
//! - [`MemFs`]: ephemeral in-memory filesystem. supports DAV properties.
//!
//! Also included are two locksystems:
//!
//! - [`MemLs`]: ephemeral in-memory locksystem.
//! - [`FakeLs`]: fake locksystem. just enough LOCK/UNLOCK support for OSX/Windows.
//!
//! ## Example.
//!
//! Example server that serves the /tmp directory in r/w mode. You should be
//! able to mount this network share from Linux, OSX and Windows.
//!
//! ```no_run
//! use webdav_handler::{fakels::FakeLs, localfs::LocalFs, DavHandler};
//!
//! #[tokio::main]
//! async fn main() {
//!     let dir = "/tmp";
//!     let addr = ([127, 0, 0, 1], 4918).into();
//!
//!     let dav_server = DavHandler::new(None, LocalFs::new(dir, false, false, false), Some(FakeLs::new()));
//!     let make_service = hyper::service::make_service_fn(move |_| {
//!         let dav_server = dav_server.clone();
//!         async move {
//!             let func = move |req| {
//!                 let dav_server = dav_server.clone();
//!                 async move {
//!                     dav_server.handle(req).await
//!                 }
//!             };
//!             Ok::<_, hyper::Error>(hyper::service::service_fn(func))
//!         }
//!     });
//!
//!     println!("Serving {} on {}", dir, addr);
//!     let _ = hyper::Server::bind(&addr)
//!         .serve(make_service)
//!         .await
//!         .map_err(|e| eprintln!("server error: {}", e));
//! }
