Enum zbus::fdo::RequestNameFlags [−][src]
#[repr(u32)] pub enum RequestNameFlags { AllowReplacement, ReplaceExisting, DoNotQueue, }
Expand description
The flags used by the bus request_name
method.
Variants
If an application A specifies this flag and succeeds in becoming the owner of the name, and
another application B later calls request_name
with the ReplaceExisting
flag, then
application A will lose ownership and receive a org.freedesktop.DBus.NameLost
signal, and
application B will become the new owner. If AllowReplacement
is not specified by
application A, or ReplaceExisting
is not specified by application B, then application B
will not replace application A as the owner.
Try to replace the current owner if there is one. If this flag is not set the application
will only become the owner of the name if there is no current owner. If this flag is set,
the application will replace the current owner if the current owner specified
AllowReplacement
.
Without this flag, if an application requests a name that is already owned, the application will be placed in a queue to own the name when the current owner gives it up. If this flag is given, the application will not be placed in the queue, the request for the name will simply fail. This flag also affects behavior when an application is replaced as name owner; by default the application moves back into the waiting queue, unless this flag was provided when the application became the name owner.
