Function compute 

Source 
pub fn compute(
    authorship: &[FileAuthorship],
    coverage_threshold: f64,
    emit_author_details: bool,
    author_hash_key: Option<&AuthorHashKey>,
) -> BusFactor
Available on crate feature vcs-git only.
Expand description

Compute the bus-factor aggregate over every file’s authorship.

coverage_threshold is clamped into the open interval (0, 1) defensively (front ends validate it); emit_author_details opts the hashed key-developer lists into the output. author_hash_key, when present, hardens those emitted ids into a keyed HMAC (issue #956) without affecting the bus-factor count or the tie-break order, both of which stay keyed on the unkeyed digest so they remain key-independent and cache-replay-stable.
