impl Compression

const fn new(level: u32) -> Self

Create a new compression spec with a specific numeric level in the range 1..=9.

Panics

A level outside of the 1..=9 range will throw a panic. Use Self::try_new to gracefully handle invalid levels (e.g. from user input).

const fn try_new(level: u32) -> Option<Self>

Create a new compression spec with a specific numeric level in the range 1..=9.

fn none() -> Self

Do not compress.

const fn fast() -> Self

Optimize for the best speed of encoding.

const fn best() -> Self

Optimize for smallest output size.

const fn level(&self) -> u32

Return the compression level as an integer.
