Struct alsa::seq::EvQueueControl

pub struct EvQueueControl<T> {
    pub queue: i32,
    pub value: T,
}

snd_seq_ev_queue_control_t wrapper

Note: This struct is generic, but what types of T are required for the different EvQueueControl messages is not very well documented in alsa-lib. Right now, Tempo is i32, Tick, SetposTick and SyncPos are u32, SetposTime is time::Duration, and the rest is (). If I guessed wrong, let me know.

Fields

queue: i32

value: T
