zbus 5.3.0

//! D-Bus standard interfaces.
//!
//! The D-Bus specification defines the message bus messages and some standard interfaces that may
//! be useful across various D-Bus applications. This module provides their proxy.

/// Proxy for the `org.freedesktop.DBus.Monitoring` interface.

pub trait Monitoring {
    /// Converts the connection into a monitor connection which can be used as a
    /// debugging/monitoring tool.

    /// After this call successfully returns, sending any messages on the bus will result
    /// in an error. This is why this method takes ownership of `self`, since there is not
    /// much use for the proxy anymore. It is highly recommended to convert the underlying
    /// [`Connection`] to a [`MessageStream`] and iterate over messages from the stream,
    /// after this call.
    ///
    /// See [the spec] for details on all the implications and caveats.
    ///
    /// # Arguments
    ///
    /// * `match_rules` - A list of match rules describing the messages you want to receive. An
    ///   empty list means you are want to receive all messages going through the bus.
    /// * `flags` - This argument is currently unused by the bus. Just pass a `0`.
