Crate sqlw 

Compile-time SQL query building for Rust.

This crate provides a compile-time SQL macro with schema-safe field references and automatic parameter binding.

Quick Start

use sqlw::{schema, query_qmark as query};

// Define your table schema
schema!(User "users" {
    ID: i64 "id",
    NAME: String "name",
    EMAIL: String "email",
});

// Build queries with schema-safe field references
let user_id = 42;
let query = query!(
    SELECT User::NAME, User::EMAIL
    FROM User::TABLE
    WHERE User::ID = {user_id}
);

query.sql();   // "SELECT name, email FROM users WHERE id = ?"
query.args();  // [Int(42)]
