Trait CompressionLevel 

pub trait CompressionLevel<T: Display + PartialOrd> {
    const MINIMUM_LEVEL: T;
    const MAXIMUM_LEVEL: T;

    // Provided method
    fn is_valid_level(level: T) -> PolarsResult<()> { ... }
}

Defines valid compression levels.

Required Associated Constants

const MINIMUM_LEVEL: T

const MAXIMUM_LEVEL: T

Provided Methods

fn is_valid_level(level: T) -> PolarsResult<()>

Tests if the provided compression level is valid.
