Function run 

pub fn run(
    opts: &RunOptions,
    decl: &Declarations,
    log: &(dyn Fn(String) + Sync),
) -> Result<(Vec<PathBuf>, Vec<String>), String>

Run a live suite: every job not yet recorded, parallel at a time, control and treatment of one task and repetition side by side so that both meet the provider under the same conditions. Returns the records written and the jobs that failed to produce one. Refuses, before any workspace exists, force (a recorded run is never written over), an unknown suite, a suite that is not live, a task the suite names but nobody declared, and a work directory — or a system temporary directory — inside the repository.
