ormx

lightweight macros for sqlx

getting started

Add ormx and sqlx to your Cargo.toml

[dependencies.ormx]
version = "0.7"
features = ["mysql"]

[dependencies.sqlx]
version = "0.5"
default-features = false
features = ["macros", "mysql", "runtime-tokio-rustls"]

Right now, ormx supports mysql/mariadb and postgres.

what does it do?

ormx provides macros for generating commonly used sql queries at compile time.
ormx is meant to be used together with sqlx. Everything it generates uses sqlx::query! under the hood, so every generated query will be checked against your database at compile time.

what doesn't it do?

ormx is not a full-fledged ORM nor a query builder. For everything except simple CRUD, you can always just use sqlx.

it is required that every table contains an id column, which uniquely identifies a row. probably, you would want to use an auto-incrementing integer for this. this is a central requirement of ormx, and if your table does not fulfill this requirement, ormx is not what you are looking for.

help

if you encounter an issue or have questions, feel free to ask in #ormx on the sqlx discord.

migration guide for 0.7

Since 0.7, id columns are not special anymore - if they are generated by the database, you must annotete them with #[ormx(default)].

a note on reborrowing

if you run into the issue that the compiler tells you that you can't re-use a &mut Connection because

use of moved value and
move occurs because 'con' has type '&mut Connection', which does not implement the 'Copy' trait

you'll have to manually reborrow the connection with &mut *con.
