#![doc(html_root_url = "https://docs.rs/webdav-handler/0.2.0")]
//! ## Generic async HTTP/Webdav handler
//!
//! [`Webdav`] (RFC4918) is defined as
//! HTTP (GET/HEAD/PUT/DELETE) plus a bunch of extension methods (PROPFIND, etc).
//! These extension methods are used to manage collections (like unix directories),
//! get information on collections (like unix `ls` or `readdir`), rename and
//! copy items, lock/unlock items, etc.
//!
//! A `handler` is a piece of code that takes a `http::Request`, processes it in some
//! way, and then generates a `http::Response`. This library is a `handler` that maps
//! the HTTP/Webdav protocol to the filesystem. Or actually, "a" filesystem. Included
//! is an adapter for the local filesystem (`localfs`), and an adapter for an
//! in-memory filesystem (`memfs`).
//!
//! So this library can be used as a handler with HTTP servers like [hyper],
//! [warp], [actix-web], etc. Either as a correct and complete HTTP handler for
//! files (GET/HEAD) or as a handler for the entire Webdav protocol. In the latter case, you can
//! mount it as a remote filesystem: Linux, Windows, macOS can all mount Webdav filesystems.
//!
//! ## Backend interfaces.
//!
//! The backend interfaces are similar to the ones from the Go `x/net/webdav package`:
//!
//! - the library contains a [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 webdav locks.
//!
//! The handler in this library works with the standard http types
//! from the `http` and `http_body` crates. That means that you can use it
//! straight away with http libraries / frameworks that also work with
//! those types, like hyper. Compatibility modules for [actix-web][actix-compat]
//! and [warp][warp-compat] are also provided.
//!
//! ## 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 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 macOS/Windows.
//!
//! ## Example.
//!
//! Example server using [hyper] that serves the /tmp directory in r/w mode. You should be
//! able to mount this network share from Linux, macOS and Windows. [Examples][examples]
//! for other frameworks are also available.
//!
//! ```no_run
//! use std::convert::Infallible;
//! 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::builder()
//!         .filesystem(LocalFs::new(dir, false, false, false))
//!         .locksystem(FakeLs::new())
//!         .build_handler();
//!
//!     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 {
//!                     Ok::<_, Infallible>(dav_server.handle(req).await)
//!                 }
//!             };
//!             Ok::<_, Infallible>(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));
