Enum Filter 

#[non_exhaustive]
pub enum Filter {
    Auto,
    Level {
        level: u8,
        sharpness: u8,
    },
    Off,
}

The loop filter strength the encoder signals in the frame header.

A key frame encoder signals the filter and leaves the decoder to run it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Signal level 0 and sharpness 0 at version 0.1.0.

Level

Signal an exact level and sharpness.

Fields

level: u8

Filter level, saturated at 63.

sharpness: u8

Filter sharpness, saturated at 7.

Off

Signal level 0, which leaves the decoder’s filter idle.
