Struct Counted 

pub struct Counted {
    pub min: u64,
    pub max: u64,
    pub runs: u32,
}

Instruction counts from repeated cachegrind runs.

Fields

min: u64

max: u64

runs: u32

Implementations

impl Counted

pub fn spread_pct(&self) -> f64

Relative spread across runs, as a percentage of the minimum.

pub fn is_suspect(&self) -> bool

Whether this subject looks non-hermetic.

The metric is deterministic; the program being measured need not be. A CLI that checks for updates, reads a cache it may have just created, or resolves DNS retires a different number of instructions depending on conditions that have nothing to do with the code under test.

Trait Implementations

impl Clone for Counted

fn clone(&self) -> Counted

impl Debug for Counted

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