Struct CoverageReport 

pub struct CoverageReport {
    pub total: usize,
    pub mir_covered: usize,
    pub hir_fallback: usize,
}

How many fns the MIR walker can emit standalone vs how many need HIR fallback. Pre-wire-up signal so callers can track walker reach across the shipped corpus without altering the codegen path.

Fields

total: usize

Total fn count in the lowered program.

mir_covered: usize

Fns whose entire body the walker emits standalone (no None anywhere in the recursive walk).

hir_fallback: usize

Fns the walker can’t emit — the recursive walk hit at least one variant that returned None. Caller would fall back to the HIR walker in a wire-up.

Implementations

impl CoverageReport

pub fn ratio(&self) -> f64

Walker reach as a percentage of total fns. 0.0 when the program is empty (no fns lowered).
