Struct fdeflate::compress::StoredOnlyCompressor

pub struct StoredOnlyCompressor<W> {
    writer: W,
    checksum: Adler32,
    block_bytes: u16,
}

Compressor that only writes the stored blocks.

This is useful for writing files that are not compressed, but still need to be wrapped in a zlib stream.

Fields

writer: W

checksum: Adler32

block_bytes: u16

Implementations

impl<W: Write + Seek> StoredOnlyCompressor<W>

pub fn new(writer: W) -> Result<Self>

Creates a new StoredOnlyCompressor that writes to the given writer.

fn set_block_header(&mut self, size: u16, last: bool) -> Result<()>

pub fn write_data(&mut self, data: &[u8]) -> Result<()>

Writes the given data to the underlying writer.

pub fn finish(self) -> Result<W>

Finish writing the final block and return the underlying writer.

impl<W> StoredOnlyCompressor<W>

pub fn compressed_size(raw_size: usize) -> usize

Return the number of bytes that will be written to the output stream for the given input size. Because this compressor only writes stored blocks, the output size is always slightly larger than the input size.
