1//! Random effect handlers
2//!
3//! This module provides standard implementations of the `RandomEffects` trait
4//! defined in `aura-core`. These handlers can be used by choreographic applications
5//! and other Aura components.
6//!
7//! Note: This module legitimately uses `rand::thread_rng()` as it implements the
8//! RandomEffects trait - this is the effect handler layer where actual system
9//! randomness is provided.
