Struct GroupDifference

Source

pub struct GroupDifference {
    pub lz_matches: i64,

    pub estimated_size: i64,
    pub zstd_size: i64,
    pub original_size: i64,
}

Expand description

Represents the difference between 2 groups of fields. For the raw values of a single group, see GroupComparisonMetrics.

This can be used for representing the difference between either splits, or any two arbitrary groups of analyzed bytes. Usually this is the difference between a result and a baseline.

Fields§

§lz_matches: i64

The difference in LZ matches.

§entropy: f64

The difference in entropy

§estimated_size: i64

Difference in estimated size using the user provided estimate function.

§zstd_size: i64

Difference in zstd compressed size

§original_size: i64

Difference in original size
