Source§impl CompressionInfo
impl CompressionInfo
pub fn new( chunk_size: u64, compressed_size: u64, offsets: &[u64], compression_algorithm: CompressionAlgorithm, ) -> Result<Self, ChunkedArchiveError>
Sourcepub fn chunk_size(&self) -> u64
pub fn chunk_size(&self) -> u64
Returns the chunk size for this compressed blob.
Sourcepub fn compressed_size(&self) -> u64
pub fn compressed_size(&self) -> u64
Returns the total compressed size of this blob.
Sourcepub fn compressed_range_for_uncompressed_range(
&self,
range: &Range<u64>,
) -> Result<Range<u64>, ChunkedArchiveError>
pub fn compressed_range_for_uncompressed_range( &self, range: &Range<u64>, ) -> Result<Range<u64>, ChunkedArchiveError>
Returns the compressed range for the specified uncompressed range.
Sourcepub fn decompress<'a>(
&self,
src: impl Into<PtrByteSlice<'a>>,
dst: &mut [u8],
dst_start_offset: u64,
) -> Result<(), ChunkedArchiveError>
pub fn decompress<'a>( &self, src: impl Into<PtrByteSlice<'a>>, dst: &mut [u8], dst_start_offset: u64, ) -> Result<(), ChunkedArchiveError>
Decompress the bytes of src into dst.
srcis allowed to span multiple chunks.dstmust have the exact size of the uncompressed bytes.dst_start_offsetis the location of the uncompressed bytes within the blob and must be chunk aligned. This is necessary for determining the chunk boundaries insrc.
