Struct Report 

pub struct Report {
    pub rows: Vec<(String, f64, f64)>,
    pub units: Vec<Unit>,
}

What changed from a to b.

Fields

rows: Vec<(String, f64, f64)>

(what, before, after), µs or a count.

units: Vec<Unit>

Each row’s unit, by index; a row past its end is Unit::Us.

Implementations

impl Report

pub fn push( &mut self, what: impl Into<String>, unit: Unit, before: f64, after: f64, )

Adds a row.

pub fn unit(&self, i: usize) -> Unit

Row i’s unit.

pub fn growth(&self, i: usize) -> Option<f64>

Row i’s growth as a fraction of its before, when it counts.

pub fn text(&self) -> String

The report as text, a row a line, marking a counted row that grew or shrank past MARK.

pub fn text_with(&self, threshold: f64) -> String

The report as text, marking a counted row whose change passes threshold (a fraction): ▲ grew, ▼ shrank.

pub fn worst_growth(&self) -> f64

The largest growth of any row, as a fraction of its before: over the rows that count (Unit::counts), 0 when none does.
