#[repr(i32)]
pub enum CompressionLevel {
    NoCompression,
    BestSpeed,
    BestCompression,
    UberCompression,
    DefaultLevel,
    DefaultCompression,
}

Expand description

How much processing the compressor should do to compress the data. NoCompression and Bestspeed have special meanings, the other levels determine the number of checks for matches in the hash chains and whether to use lazy or greedy parsing.

Variants

`NoCompression`

Don’t do any compression, only output uncompressed blocks.

`BestSpeed`

Fast compression. Uses a special compression routine that is optimized for speed.

`BestCompression`

Slow/high compression. Do a lot of checks to try to find good matches.

`UberCompression`

Even more checks, can be very slow.

`DefaultLevel`

Default compromise between speed and compression.

`DefaultCompression`

Use the default compression level.
