Struct MaintainabilityIndex 

pub struct MaintainabilityIndex {
    pub score: f64,
    pub avg_cyclomatic: f64,
    pub avg_loc: f64,
    pub avg_halstead_volume: Option<f64>,
    pub grade: String,
}

Composite maintainability index based on the SEI formula.

MI = 171 - 5.2 * ln(V) - 0.23 * CC - 16.2 * ln(LOC)

When Halstead volume is unavailable, a simplified formula is used.

Fields

score: f64

Maintainability index score (0-171 scale, higher is better).

avg_cyclomatic: f64

Average cyclomatic complexity used in calculation.

avg_loc: f64

Average lines of code per file used in calculation.

avg_halstead_volume: Option<f64>

Average Halstead volume (if Halstead metrics were computed).

grade: String

Letter grade: “A” (>=85), “B” (65-84), “C” (<65).
