Struct alsa::seq::Event
[−]
[src]
pub struct Event<'a>(_, _, _);
snd_seq_event_t wrapper
Fields of the event is not directly exposed. Instead call Event::new to set data (which can be, e g, an EvNote).
Use get_type and get_data to retreive data.
The lifetime parameter refers to the lifetime of an associated external buffer that might be used for variable-length messages (e.g. SysEx).
Methods
impl<'a> Event<'a>[src]
fn new<D: EventData>(t: EventType, data: &D) -> Event<'static>
Creates a new event. For events that carry variable-length data (e.g. Sysex), new_ext has to be used instead.
fn new_ext<D: Into<Cow<'a, [u8]>>>(t: EventType, data: D) -> Event<'a>
Creates a new event carrying variable-length data. This is required for event types Sysex, Bounce, and the UsrVar types.
fn into_owned(self) -> Event<'static>
Consumes this event and returns an (otherwise unchanged) event where the externally referenced buffer for variable length messages (e.g. SysEx) has been copied into the event. The returned event has a static lifetime, i e, it's decoupled from the original buffer.
fn get_type(&self) -> EventType
fn get_data<D: EventData>(&self) -> Option<D>
Extract the event data from an event.
Use get_ext instead for events carrying variable-length data.
fn get_ext<'b>(&'b self) -> Option<&'b [u8]>
Extract the variable-length data carried by events of type Sysex, Bounce, or the UsrVar types.
fn set_subs(&mut self)
fn set_source(&mut self, p: i32)
fn set_dest(&mut self, d: Addr)
fn set_tag(&mut self, t: u8)
fn set_queue(&mut self, q: i32)
fn get_source(&self) -> Addr
fn get_dest(&self) -> Addr
fn get_tag(&self) -> u8
fn get_queue(&self) -> i32
fn schedule_real(&mut self, queue: i32, relative: bool, rtime: Duration)
fn schedule_tick(&mut self, queue: i32, relative: bool, ttime: u32)
fn set_direct(&mut self)
fn get_relative(&self) -> bool
fn get_time(&self) -> Option<Duration>
fn get_tick(&self) -> Option<u32>
fn get_priority(&self) -> bool
Returns true if the message is high priority.
fn set_priority(&mut self, is_high_prio: bool)
