Command-line tool to make Rust source code entities from Postgres tables. Generates:
- enums
- structs
which can be then used like
mod structs;
use structs::{User};
let result = client.query("SELECT * FROM \"Users\"", &[]).await.unwrap();
let users: Vec<User> = result.into_iter().map(|row| User::from(row)).collect();
println!("{:#?}", users);
It is not an ORM, main purpose is to have tables DDL as a source of truth. DDL can be generated using some tool like Alembic, and then pg2rs is used to reflect changes in your structs.rs
