Struct CompressOptions 

pub struct CompressOptions {
    pub level: Option<i32>,
    pub window_log: Option<u32>,
}

Compression tuning options passed to low-level compression functions.

Carries optional overrides for quality/level and window size. None means use the codec’s built-in default.

Fields

level: Option<i32>

Compression level / quality override.

For Brotli: 0-11 (default 6). For Zstd: -131072..=22 (default 3). Ignored for Snappy and CompressionType::None.

window_log: Option<u32>

Window size (log2 of window size in bytes).

For Brotli: 10-30 (default 22, mapped to lgwin). For Zstd: 10-31 (default 0 = automatic, mapped to window_log). Must be None for Snappy and CompressionType::None.
