[−][src]Struct zstd_seekable::SeekableCStream
The type of seekable compressors.
Implementations
impl SeekableCStream
[src]
pub fn new(level: usize, frame_size: usize) -> Result<Self, Error>
[src]
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>
[src]
&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>
[src]
Finish writing the message, i.e. write the remaining pending block.
