Function interleave_unchecked 

pub unsafe fn interleave_unchecked<T: Copy, Vin: AsRef<[T]>, const CHANNELS: usize>(
    input: &[Vin],
    input_range: Range<usize>,
    output: &mut [T],
)

Interleave the given channels into the output buffer.

No bounds checking will occur.

• input - The de-interleaved input channels.
• input_range - The range in each input channel to read from.
• output - The interleaved output buffer to write to.

Example

let input: Vec<Vec<i32>> = vec![vec![1, 3, 5, 7], vec![2, 4, 6, 8]];
let mut output: Vec<i32> = vec![0; 8];

unsafe { interleave_unchecked::<_, _, 2>(&input, 0..4, &mut output); }

assert_eq!(&output, &[1, 2, 3, 4, 5, 6, 7, 8]);

// Interleave range in input:
unsafe { interleave_unchecked::<_, _, 2>(&input, 2..4, &mut output[0..4]); }

assert_eq!(&output, &[5, 6, 7, 8, 5, 6, 7, 8]);

Safety

The caller must uphold that all of the following conditions are true:

• input.len() >= CHANNELS
• input_range is within bounds for every input channel
• output.len() >= (input_range.end - input_range.start) * CHANNELS
• CHANNELS > 0
