Struct alsa::seq::Input

source ·
pub struct Input<'a>(/* private fields */);
Expand description

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.
