Expand description

Comprehensive entropy metrics for a byte sequence.

Fields§

§shannon_entropy: f64

Shannon entropy in bits per byte (0.0–8.0, 8.0 = perfectly random).

§min_entropy: f64

Min-entropy in bits per byte (most conservative estimate).

§collision_entropy: f64

Collision entropy (Renyi order-2) in bits per byte.

§chi_squared: f64

Chi-squared test statistic.

§chi_squared_p: f64

Chi-squared p-value (1.0 = perfectly uniform).

§serial_correlation: f64

Serial correlation coefficient (-1.0 to 1.0, 0.0 = uncorrelated).

§longest_run: usize

Longest run of identical bits.

§bit_bias: f64

Fraction of bits that are 1 (should be ~0.5).

§unique_bytes: usize

Number of unique bytes observed.
