[dependabot]

Bumps zbus from 3.15.0 to 4.0.0.

Release notes

Sourced from zbus's releases.

🔖 zbus 4.0.0

A new API-breaking release that brings in a huge amount of changes. Most using code should still compile (with deprecation warnings) and work without changes. Hightlights:

• 🚚 Changing names of dbus_interface and dbus_proxy along with their atrributes. See [zbus_macros release notes][zmr] for details, including commands to automatically update your code.
• 👽️ Adapt to zvariant 4.0 changes.
• 🚚 Make use of submodules for nicer API hierarchy. In most cases deprecation warnings will guide you to the new paths.
• 🚚 XML parsing API split into a separate crate, zbus_xml. The xml and quick-xml feature flags are removed as a result. #413.
• 🏗️ Message API overhaul
  • 🚸 header method and message::Header getters now infallible.
  • 🏷️ body method now returns a new type, message::Body that provides all message body-related API.
  • 🔥 MessageField* API dropped. Use Message::header() with message::Header's specific getters.
  • 🔥 message::Type::Invalid variant dropped. We just don't let a message be created for invalid types.
  • 🚚 as_bytes method renamed to data and now returns &zvariant::serialized::Data.
  • 🔥 Drop Message::take_fds() method. This was never a good idea because it is basically unsafe (even though it's not marked as such) since it disassociates the FDs from the message and the caller is free to close them while message is still referencing them.
  • 🏷️ All serial number related API now use NonZeroU32.
  • 🚸 constructors now return a Builder instance.
  • 🚸 Arc wrapping of message no longer needed and all API using Arc type now use Message.
  • 🔥 Drop unneeded From for message::Type.
• 🔌 Connection
  • 🔥 Drop futures::Sink implementation. This was proving very difficult to maintain and most likely used by very few people, who can use the send method instead.
  • 🏷️ server_guid return &Guid now, instead of a string.
  • 🥅 connection::Builder::server now takes anything TryInto and hence fallible.
  • 🥅 connection::Builder ensures GUID is correct for client: If the client connection is constructed through an address with GUID in it, we should verify this GUID is the same as one received from the server during the handshake.
  • 🏗️ Socket trait now higher-level, async and split into read and write halves.
  • 🔥 Remove unnecessary constraints on Socket. and associated types.
  • ✨ Add missing blocking::connection::Builder::socket.
  • ✨ Proper support for abstract unix sockets that makes use of the std API. This replaces our hack.
• 💥 Split Guid into reference & owned types. Guid now has a lifetime parameter, and OwnedGuid is a new type that's a wrapper around Guid<'static>. Internally, Guid is now a wrapper around zvariant::Str and is now a very similar type to other zvariant::Str wrapper types.
• 🏗️ Address API overhaul:
  • 💥 Split transport bits into a separate type hierarchy, address::Transport. Address` is no longer an enum but a struct with hidden fields. #476.
  • ✨ Support GUIDs. We previously just ignored GUIDs in addresses. No more. We now parse it, if present and provide API to set a GUID on an Address instance.
  • ✨ Support unix:tmpdir and unix:dir transports.
  • 🐛 Fix Display impl for address of abstract Unix sockets.
• ✨ Relax type bound on Proxy::call/call_with_flags. A bound of
