Function plan_mutations_for_session_with 

pub fn plan_mutations_for_session_with(
    session: &AnalysisSession,
    request: &MutationPlanRequest,
    skip_components: impl FnOnce(&MutationPlan) -> bool,
) -> Result<MutationPlan, MutationPlanError>

Like plan_mutations_for_session, but skip_components reads the first plan and decides if the component files leave the plan. The test runner can depend on the test files of the plan, so the caller decides after the first plan. When the first plan has a component mutant and skip_components returns true, the plan is built again from the same analysis with MutationPlanRequest::skip_component_files set.

Errors

Returns an error when the analysis or the plugin stage fails.
