Function rle_decode

pub fn rle_decode<T>(
    buffer: &mut Vec<T>,
    lookbehind_length: usize,
    fill_length: usize,
)
where
    T: Copy,

Fast decoding of run length encoded data

Takes the last lookbehind_length items of the buffer and repeatedly appends them until fill_length items have been copied.

Panics

• lookbehind_length is 0
• lookbehind_length >= buffer.len()
• fill_length + buffer.len() would overflow
