Struct GroupDifference

pub struct GroupDifference {
    pub lz_matches: i64,
    pub entropy: f64,
    pub estimated_size: i64,
    pub zstd_size: i64,
    pub original_size: i64,
}

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

Implementations

impl GroupDifference

pub fn from_metrics( baseline: &GroupComparisonMetrics, comparison: &GroupComparisonMetrics, ) -> Self

Creates a new GroupDifference by comparing two sets of metrics

Arguments

• baseline - The baseline metrics to compare against
• comparison - The metrics to compare with the baseline

Returns

A new GroupDifference containing the calculated differences

Trait Implementations

impl Clone for GroupDifference

fn clone(&self) -> GroupDifference

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GroupDifference

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GroupDifference

fn default() -> GroupDifference

Returns the “default value” for a type.

impl PartialEq for GroupDifference

fn eq(&self, other: &GroupDifference) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for GroupDifference
