Function locate 

pub fn locate(
    start: &Path,
    opts: &Options,
    feature: &str,
    task: &str,
) -> Result<Checked, Refusal>

One task of feature at the head, for its tour: checked with the caller’s trust when given, else read as recorded (signatures not checked, said in its detail). The report holds that tick alone, or none.

Errors

As check, except that no trust is no refusal.
