Add this to your Cargo.toml:

[dependencies]
vibesql-ast = "0.1"

Basic example:

use vibesql_ast::{SelectStmt, Expression};

// AST nodes represent SQL structures
let expr = Expression::BinaryOp {
    left: Box::new(Expression::Identifier("age".to_string())),
    op: BinaryOperator::GreaterThan,
    right: Box::new(Expression::Literal(SqlValue::Integer(18))),
};
