4//! Core sampling logic for Datadog tracing
5//!
6//! This crate provides generic sampling infrastructure including:
7//! - Trait abstractions for trace IDs, attributes, and span properties
8//! - Rate-based sampling algorithms
9//! - Rate limiting functionality
10//! - Glob pattern matching for sampling rules
11//! - Sampling-related constants
12//! - Rule-based sampling with pattern matching
13//! - Agent-provided sampling rates
14//! - Complete Datadog sampler implementation
