Struct ShuffleCodec 

pub struct ShuffleCodec {
    pub element_size: usize,
}

Byte-shuffle filter: rearranges bytes for better compression.

Groups byte k of each element together, so e.g. for 4-byte floats all MSBs are contiguous, then next bytes, etc.

Fields

element_size: usize

Element size in bytes.
