DecompressError	An error representing invalid compressed data.

Functions

compress	Compress all bytes of input.
compress_into	Compress all bytes of input into output. The method chooses an appropriate hashtable to lookup duplicates and calls compress_into_with_table. output should be preallocated with a size of get_maximum_output_size.
compress_into_with_dict	Compress all bytes of input into output. The method chooses an appropriate hashtable to lookup duplicates and calls compress_into_with_table. output should be preallocated with a size of get_maximum_output_size.
compress_prepend_size	Compress all bytes of input into output. The uncompressed size will be prepended as a little endian u32. Can be used in conjunction with decompress_size_prepended
compress_prepend_size_with_dict	Compress all bytes of input into output. The uncompressed size will be prepended as a little endian u32. Can be used in conjunction with decompress_size_prepended_with_dict
compress_with_dict	Compress all bytes of input with an external dictionary.
decompress	Decompress all bytes of input into a new vec.
decompress_into	Decompress all bytes of input into output. output should be preallocated with a size of of the uncompressed data.
decompress_into_with_dict	Decompress all bytes of input into output.
decompress_size_prepended	Decompress all bytes of input into a new vec. The first 4 bytes are the uncompressed size in litte endian. Can be used in conjunction with compress_prepend_size
decompress_size_prepended_with_dict	Decompress all bytes of input into a new vec. The first 4 bytes are the uncompressed size in little endian. Can be used in conjunction with compress_prepend_size_with_dict
decompress_with_dict	Decompress all bytes of input into a new vec.
get_maximum_output_size	Returns the maximum output size of the compressed data. Can be used to preallocate capacity on the output vector
