Struct Encoder

pub struct Encoder { /* private fields */ }

A huffman encoder that writes successive tables and data to pages

Implementations

impl Encoder

pub fn new(page_size: usize, page_threshold: usize) -> Encoder

Create an encoder that writes into pages of page_size bytes and rebuilds the frequency table every page_threshold pages.

pub fn reset(&mut self)

Prepare the encoder for a new round of encoding this keeps allocations, so its cheaper than a Encoder::new call

pub fn batch_fits(&self, bytes: usize) -> bool

Check if a batch of bytes fits in the current batch

pub unsafe fn batch_sink(&mut self, bytes: &[u8])

Sink a batch of bytes without checking if the batch fits

pub async fn sink<E>( &mut self, byte: u8, output: &mut impl PageWriter<E>, ) -> Result<bool, E>

Put a byte into the encoder

pub async fn flush<E>( &mut self, output: &mut impl PageWriter<E>, ) -> Result<bool, E>

Finish encoding and flush any remaining bytes
