Struct sndjvu_codec::bzz::dec::Shuffle

pub struct Shuffle<'scratch> { /* private fields */ }

Available on crate feature bzz only.

State of the decoder after the initial decoding pass over a block.

A second pass over the decoded data is needed to compute the output bytes, and this is implemented by Self::run. This doesn’t need further access to the input byte stream, so decoding of the next block can proceed in parallel.

Implementations

impl<'scratch> Shuffle<'scratch>

pub fn len(&self) -> usize

The length of the output block.

pub fn run(self, out: &mut [u8])

Run the inverse Burrows–Wheeler transform to compute the output block.

The length of out must be equal to self.len().
