#[repr(C)]pub struct CompressionOptions {

Compression options for different compression algorithms like Zlib

Fields

window_bits: c_intlevel: c_intstrategy: c_intmax_dict_bytes: u32

Maximum size of dictionary used to prime the compression library. Currently this dictionary will be constructed by sampling the first output file in a subcompaction when the target level is bottommost. This dictionary will be loaded into the compression library before compressing/uncompressing each data block of subsequent files in the subcompaction. Effectively, this improves compression ratios when there are repetitions across data blocks. A value of 0 indicates the feature is disabled. Default: 0.
