17//! # IDN Traits
18//!
19//! Core traits for the Ideal Network (IDN) ecosystem.
20//!
21//! This crate provides fundamental interfaces for handling randomness pulses.
22//!
23//! ## Modules
24//!
25//! * [`pulse`] - Traits and types for randomness pulses handling and distribution
26//!
27//! ## Overview
28//!
29//! The IDN traits define the foundational interfaces that allow different
30//! components of the system to interact in a standardized way. These traits
31//! enable a modular architecture where randomness sources, dispatchers, and
32//! consumers can all operate together seamlessly.
