Struct libdeflater::CompressionLvl

pub struct CompressionLvl(_);

Compression level used by a Compressor instance.

Implementations

impl CompressionLvl

pub fn new(level: i32) -> Result<CompressionLvl, CompressionLvlError>

Try to create a valid CompressionLvl from a numeric value.

If level is a valid custom compression level for libdeflate, returns a Result::Ok(CompressionLvl). Otherwise, returns Result::Error(error).

Valid compression levels for libdeflate, at time of writing, are 1-12.

pub fn fastest() -> CompressionLvl

Returns the fastest compression level. This compression level offers the highest performance but lowest compression ratio.

pub fn best() -> CompressionLvl

Returns the best compression level, in terms of compression ratio. This compression level offers the best compression ratio but lowest performance.

pub fn iter() -> CompressionLvlIter

Returns an iterator that emits all compression levels supported by libdeflate in ascending order.
