Macro audio::dynamic

macro_rules! dynamic {
    ([$sample:expr; $frames:literal]; $channels:literal) => { ... };
    ([$sample:expr; $frames:expr]; $channels:expr) => { ... };
    ([$($value:expr),* $(,)?]; $channels:expr) => { ... };
    ($($channel:expr),* $(,)?) => { ... };
}

Construct an audio buffer.

This is useful when testing.

Examples

let buf = audio::dynamic![[0; 64]; 2];

let mut expected = vec![0; 64];

assert_eq!(&buf[0], &expected[..]);
assert_eq!(&buf[1], &expected[..]);

Calling the macro with a template channel.

let buf = audio::dynamic![[0, 1, 2, 3]; 2];

assert_eq!(&buf[0], &[0, 1, 2, 3]);
assert_eq!(&buf[1], &[0, 1, 2, 3]);

Using an exact topology of channels.

let buf = audio::dynamic![[0, 1, 2, 3], [4, 5, 6, 7]];

assert_eq!(&buf[0], &[0, 1, 2, 3]);
assert_eq!(&buf[1], &[4, 5, 6, 7]);
