Fields

random: Arc<dyn Random + Sync + Send + 'static>

A wrapper on random generator.

quota: Option<Arc<dyn Quota + Sync + Send + 'static>>

A global execution quota.

parallelism: Parallelism

Keeps data parallelism settings.

logger: Arc<dyn Fn(&str) + Sync + Send + 'static>

An information logger.

is_experimental: bool

A boolean flag which signalizes that experimental behavior is allowed.

Implementations
