Module tuple 

An atom containg a series of other atoms.

This atom is just like a sequence, only without time stamps: It contains multiple arbitrary atoms which you can either iterate through or write in sequence.

Example

use lv2_core::prelude::*;
use lv2_atom::prelude::*;
use lv2_atom::tuple::{TupleIterator, TupleWriter};

#[derive(PortCollection)]
struct MyPorts {
    input: InputPort<AtomPort>,
    output: OutputPort<AtomPort>,
}

fn run(ports: &mut MyPorts, urids: &AtomURIDCollection) {
    let input: TupleIterator = ports.input.read(urids.tuple, ()).unwrap();
    let mut output: TupleWriter = ports.output.init(urids.tuple, ()).unwrap();
    for atom in input {
        if let Some(integer) = atom.read(urids.int, ()) {
            output.init(urids.int, integer * 2).unwrap();
        } else {
            output.init(urids.int, -1).unwrap();
        }
    }
}
