Crate lref 

Rust Entity Framework (lref)

An EFCore-inspired ORM for Rust, bringing the familiar DbContext/DbSet/EntityType patterns to the Rust ecosystem.

Example

use lref::prelude::*;

#[derive(EntityType)]
#[table("blogs")]
pub struct Blog {
    #[primary_key]
    #[auto_increment]
    pub blog_id: i32,
    #[required]
    #[max_length(200)]
    pub url: String,
    pub rating: i32,
    #[navigation]
    pub posts: HasMany<Post>,
}
