Enum CompressionLevel 

#[non_exhaustive]
pub enum CompressionLevel {
    Fastest,
    Best,
    Default,
    Precise(u32),
}

Available on crate feature compression only.

Level of compression data should be compressed with.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Fastest

Fastest quality of compression, usually produces bigger size.

Best

Best quality of compression, usually produces the smallest size.

Default

Default quality of compression defined by the selected compression algorithm.

Precise(u32)

Precise quality based on the underlying compression algorithms’ qualities.

The interpretation of this depends on the algorithm chosen and the specific implementation backing it.

Qualities are implicitly clamped to the algorithm’s maximum.
