Struct alsa::seq::Event

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>

pub 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.

pub 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.

pub 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.

pub fn get_type(&self) -> EventType

pub 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.

pub 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.

pub fn get_time(&self) -> Option<Duration>

pub fn get_tick(&self) -> Option<u32>
