Struct zstd_seekable::SeekableCStream

pub struct SeekableCStream { /* fields omitted */ }

The type of seekable compressors.

Implementations

impl SeekableCStream

pub fn new(level: usize, frame_size: usize) -> Result<Self, Error>

Create a compressor with the given level and frame size. When seeking in the file, frames are decompressed one by one, so this should be chosen of a size similar to the chunks that will be decompressed.

pub fn compress(
    &mut self,
    output: &mut [u8],
    input: &[u8]
) -> Result<(usize, usize), Error>

Compress one chunk of input, and write it into the output. The output array must be large enough to hold the result. If successful, this function returns two integers (out_pos, in_pos), where out_pos is the number of bytes written in output, and in_pos is the number of input bytes consumed.

pub fn end_stream(&mut self, output: &mut [u8]) -> Result<usize, Error>

Finish writing the message, i.e. write the remaining pending block.
