//! Expression and predicate types for filtering Iceberg tables
//!
//! This module provides types for building filter predicates that can be used
//! for partition pruning and column statistics-based file filtering.
//!
//! # Example
//!
//! ```
//! use icepick::expr::{Predicate, Datum};
//!
//! // Simple equality filter
//! let filter = Predicate::eq("status", "active");
//!
//! // Range filter
//! let filter = Predicate::and([
//!     Predicate::gt_eq("date", Datum::Date(19724)), // 2024-01-01
//!     Predicate::lt("date", Datum::Date(19755)),    // 2024-02-01
//! ]);
//!
//! // Complex filter with AND/OR
//! let filter = Predicate::or([
//!     Predicate::eq("region", "us-west"),
//!     Predicate::and([
//!         Predicate::eq("region", "eu-central"),
//!         Predicate::gt("priority", 5),
//!     ]),
//! ]);
//! ```
