Implementations§

Source§

impl TimingStatistics

Source

pub fn is_constant_time(&self, threshold: f64) -> bool

Check if timing appears constant-time

Uses coefficient of variation threshold. Lower is better. Typical threshold: 0.05 (5%) for constant-time operations.

Source

pub fn z_score(&self, value_ns: u64) -> f64

Calculate z-score for a given timing value
