Struct libdeflater::CompressionLvl
source ·
[−]pub struct CompressionLvl(_);
Expand description
Compression level used by a Compressor
instance.
Implementations
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.
Returns the fastest compression level. This compression level offers the highest performance but lowest compression ratio.
Returns the best compression level, in terms of compression ratio. This compression level offers the best compression ratio but lowest performance.

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