//! # SQLx CLI
//!
//! Command-line utility for the [SQLx](https://github.com/launchbadge/sqlx) ecosystem.
//!
//! This crate provides the core logic for the `sqlx` command-line interface, enabling database management,
//! migrations, and offline query preparation for Rust projects using SQLx.
//!
//! ### Note: Semver Exempt API
//! The API of this crate is not meant for general use and does *not* follow Semantic Versioning.
//! The only crate that follows Semantic Versioning in the project is the `sqlx` crate itself.
//! If you are building a custom SQLx driver, you should pin an exact version for `sqlx-cli` to
//! avoid breakages:
//!
//! ```toml
//! sqlx-cli = { version = "=0.9.0" }
//! ```
//!
//! And then make releases in lockstep with `sqlx-cli`. We recommend all driver crates, in-tree
//! or otherwise, use the same version numbers as `sqlx-cli` to avoid confusion.
