# diesel_derive_table

This crates provides additional derive functionality for [Diesel][diesel],

an ORM for Rust.

## Why

Diesel requires you to either infer the schema from the database, dump the

database to schema definitions with a CLI command, or specify table schemas

with the `table!` macro.

Non of those options really suit my workflow.

This crate contains one custom_derive implementation, `#derive[(Table)]`.

It gives you the ability to define a struct for your table, and also auto-generate

the table! macro for diesel.

## How to use

```rust

#[macro_use] extern crate diesel_derive_table

#[derive(Table, Queryable, AsChangeset, Insertable, Identifiable)]

#[table_name="reddit_posts"]

#[primary_key(uuid)]

pub struct RedditPost {

    #[column_type="Text"]

    #[column_name="my_uuid"]

    pub uuid: String,

    #[column_type="BigInt"]

    pub created_at: i64,

}

```

Notes:

* It supports Diesel's attributes (column_name, table_name, primary_key)

* provides additional attribute `column_type` for specifying the DB column type

* Requires you to specify additional derives, so you stay in control of what

  should be derived.
