Struct alsa::seq::Input

pub struct Input<'a>(_);

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.

Methods

impl<'a> Input<'a>

fn event_input<'b>(&'b mut self) -> Result<Event<'b>>

fn event_input_pending(&self, fetch_sequencer: bool) -> Result<u32>

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

Trait Implementations

impl<'a> Drop for Input<'a>

fn drop(&mut self)

A method called when the value goes out of scope.
