====

sqly is a lightweight macro system on top of [sqlx](https://github.com/launchbadge/sqlx), inspired by [ormx](https://github.com/NyxCode/ormx).

It works by generating common SQL queries and associated structs at compile time, letting the generated queries be checked and executed by sqlx.

This crate differs from ormx mainly by the added functionality of generating SQL `SELECT` queries with support for nested objects through SQL `JOIN` clauses. Additionally, `sqly::query!` macros can be used to further expand generated queries while still providing compile-time verification.

This functionality is still under development (see [Roadmap](#roadmap)).

##### Cargo.toml
```toml
[dependencies.sqly]
version = "0.2.0"
features = ["postgres"]

[dependencies.sqlx]
version = "0.8.0"
default-features = false
features = ["macros", "postgres"]

[profile.dev.package.sqlx-macros]
opt-level = 3

[profile.dev.package.sqly-macros]
opt-level = 3
```

##### Features
`unchecked`&ensp;—&ensp;disable compile-time checking<br>
` postgres`&ensp;—&ensp;generate queries for PostgreSQL<br>
`   sqlite`&ensp;—&ensp;generate queries for SQLite (not supported)<br>
`    mysql`&ensp;—&ensp;generate queries for MySQL (not supported)

Currently only postgres is supported.
