Set of compression levels.

A compressed data stream can be decompressed with any level, but the compression level used to compress the data must be known.

The compression level controls the amount of work done by the compressor to find the best compressed bitstream. It does not directly impact decompression speed, it trades off encode speed for compression bitstream quality.

Variants

None

Don’t compress, just copy the data

SuperFast

Lowest compression ratio, super fast

VeryFast

Fastest with still decent compression ratio

Fast

Good for daily use

Normal

Standard medium speed

Optimal1

Optimal parse level 1 (fastest)

Optimal2

Optimal parse level 2 (recommended baseline)

Optimal3

Optimal parse level 3 (slower)

Optimal4

Optimal parse level 4 (very slow)

Optimal5

Optimal parse level 5 (don’t care about speed, just want best ratio)

HyperFast1

Faster than SuperFast, but lower compression ratio

HyperFast2

Faster than HyperFast1, but lower compression ratio

HyperFast3

Faster than HyperFast2, but lower compression ratio

HyperFast4

Faster than HyperFast3, but lower compression ratio

Optimal

Alias optimal standard level

HyperFast

Alias hyperfast base level

Max

Alias for the maximum compression level

Min

Alias for the minimum compression level

Trait Implementations

impl Default for CompressionLevel

fn default() -> Self

Returns the “default value” for a type.

impl Into<i32> for CompressionLevel

fn into(self) -> OodleLZ_CompressionLevel

Converts this type into the (usually inferred) input type.
