Struct alsa::seq::Seq

pub struct Seq(_, _);

[−] Expand description

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.

Methods

impl Seq

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

fn control_queue(
    &self,
    q: i32,
    t: EventType,
    value: i32,
    e: Option<&mut Event>
) -> Result<()>

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

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

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

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

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

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

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

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

fn input<'a>(&'a self) -> Input<'a>[−]

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.
