Expand description
Types and traits for easily getting a message’s arguments, or appening a message with arguments.
Also see the argument’s guide (in the examples directory) for details about which Rust types correspond to which D-Bus types.
A message has read1, read2 etc, and append1, append2 etc, which is one
starting point into this module’s types.
Modules
MessageItem - old, enum design that is used as parameters and return values from
method calls, or as data added to a signal.
Structs
Represents a D-Bus Array. Maximum flexibility (wraps an iterator of items to append).
Append a D-Bus dict type (i e, an array of dict entries).
Helper struct for retrieve one or more arguments from a Message.
Helper struct for appending one or more arguments to a Message.
An RAII wrapper around Fd to ensure that file descriptor is closed
when the scope ends. Enable the
stdfd feature to use std’s OwnedFd instead.Error struct to indicate a D-Bus argument type mismatch.
A simple wrapper to specify a D-Bus variant.
Enums
Type of Argument
Traits
Types that can be appended to a message as arguments implement this trait.
Helper trait to append many arguments to a message.
Types that can represent a D-Bus message argument implement this trait.
Helper trait to introspect many arguments.
Types that can be used as keys in a dict type implement this trait.
If a type implements this trait, it means the size and alignment is the same
as in D-Bus. This means that you can quickly append and get slices of this type.
Types that can be retrieved from a message as arguments implement this trait.
Helper trait to read all arguments from a message.
Object safe version of Arg + Append + Get.
Functions
Cast a RefArg as a specific type (shortcut for any + downcast)
Cast a RefArg as a specific type (shortcut for any_mut + downcast_mut)
Descend into a hashmap returned by e g “Properties::get_all” to retrieve the value of a property.
Type Definitions
The type typically used for a dictionary of properties.
