Struct alsa::seq::Seq

pub struct Seq(/* private fields */);

snd_seq_t wrapper

To access the functions event_input, event_input_pending and set_input_buffer_size, you first have to obtain an instance of Input by calling input(). Only one instance of Input may exist at any time for a given Seq.

Implementations

impl Seq

pub fn open( name: Option<&CStr>, dir: Option<Direction>, nonblock: bool ) -> Result<Seq>

Opens the sequencer.

If name is None, “default” will be used. That’s almost always what you usually want to use anyway.

pub fn set_client_name(&self, name: &CStr) -> Result<()>

pub fn set_client_event_filter(&self, event_type: i32) -> Result<()>

pub fn set_client_pool_output(&self, size: u32) -> Result<()>

pub fn set_client_pool_input(&self, size: u32) -> Result<()>

pub fn set_client_pool_output_room(&self, size: u32) -> Result<()>

pub fn client_id(&self) -> Result<i32>

pub fn drain_output(&self) -> Result<i32>

pub fn get_any_client_info(&self, client: i32) -> Result<ClientInfo>

pub fn get_any_port_info(&self, a: Addr) -> Result<PortInfo>

pub fn create_port(&self, port: &PortInfo) -> Result<()>

pub fn create_simple_port( &self, name: &CStr, caps: PortCap, t: PortType ) -> Result<i32>

pub fn set_port_info(&self, port: i32, info: &mut PortInfo) -> Result<()>

pub fn delete_port(&self, port: i32) -> Result<()>

pub fn subscribe_port(&self, info: &PortSubscribe) -> Result<()>

pub fn unsubscribe_port(&self, sender: Addr, dest: Addr) -> Result<()>

pub fn control_queue( &self, q: i32, t: EventType, value: i32, e: Option<&mut Event<'_>> ) -> Result<()>

pub fn event_output(&self, e: &mut Event<'_>) -> Result<u32>

pub fn event_output_buffer(&self, e: &mut Event<'_>) -> Result<u32>

pub fn event_output_direct(&self, e: &mut Event<'_>) -> Result<u32>

pub fn get_queue_tempo(&self, q: i32) -> Result<QueueTempo>

pub fn set_queue_tempo(&self, q: i32, value: &QueueTempo) -> Result<()>

pub fn get_queue_status(&self, q: i32) -> Result<QueueStatus>

pub fn free_queue(&self, q: i32) -> Result<()>

pub fn alloc_queue(&self) -> Result<i32>

pub fn alloc_named_queue(&self, n: &CStr) -> Result<i32>

pub fn sync_output_queue(&self) -> Result<()>

pub fn drop_output(&self) -> Result<()>

pub fn input(&self) -> Input<'_>

Call this function to obtain an instance of Input to access the functions event_input, event_input_pending and set_input_buffer_size. See the documentation of Input for details.

pub fn remove_events(&self, condition: RemoveEvents) -> Result<()>
