//! Concept drift detection algorithms.
//!
//! Drift detectors monitor a stream of error values and signal when the
//! underlying distribution has changed, triggering tree replacement in SGBT.
//!
//! Core types and implementations are defined in `irithyll-core` and
//! re-exported here for backward compatibility.
// Re-export core drift types and sub-modules.
