[−][src]Struct alsa::seq::Input
Struct for receiving input events from a sequencer. The methods offered by this
object may modify the internal input buffer of the sequencer, which must not happen
while an Event
is alive that has been obtained from a call to event_input
(which
takes Input
by mutable reference for this reason). This is because the event might
directly reference the sequencer's input buffer for variable-length messages (e.g. Sysex).
Note: Only one Input
object is allowed in scope at a time.
