1//! Chain Builder - A flexible and easy-to-use query builder for MySQL in Rust
2//!
3//! This library provides a fluent interface for building SQL queries with support for:
4//! - SELECT, INSERT, UPDATE, DELETE operations
5//! - Complex WHERE clauses with subqueries
6//! - JOIN operations
7//! - WITH clauses (CTEs)
8//! - UNION operations
9//! - Raw SQL support
10//!
11//! # Example
12//! ```rust
13//! use chain_builder::{ChainBuilder, Client, Select, WhereClauses};
14//! use serde_json::Value;
15//!
16//! let mut builder = ChainBuilder::new(Client::Mysql);
17//! builder
18//! .db("mydb")
19//! .select(Select::Columns(vec!["*".into()]))
20//! .table("users")
21//! .query(|qb| {
22//! qb.where_eq("name", Value::String("John".to_string()));
23//! qb.where_eq("status", Value::String("active".to_string()));
24//! });
25//!
26//! let (sql, binds) = builder.to_sql();
27//! ```
