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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
