diesel-ulid

Ulid mapping for diesel-rs and . This crate contains custom mapping for the Ulid implementation from rusty-ulid to diesel::sql_types::Uuid. With this adapter you can use these types in Diesel and tokio_postgres as regular Postgres UUID type.

Import

cargo add diesel-ulid

or add:

diesel-ulid = 0.3.1

to your Cargo.toml. While this crate was iniated for diesel-rs it can also be used with the rust-postgres driver. You can use the postgres or diesel feature to enable the corresponding adapter.

Usage

This is an adaptation of the Getting started section from diesel-rs.

Assuming you have the following schema.rs file:


diesel::table! {
    posts (id) {
        id -> Uuid,
        title -> Varchar,
        body -> Text,
        published -> Bool,
    }
}

you could use diesel-ulid as follows:

use diesel::prelude::*;
use diesel_ulid::DieselUlid as Ulid;

#[derive(Queryable)]
pub struct Post {
    pub id: Ulid,
    pub title: String,
    pub body: String,
    pub published: bool,
}

The Postgres UUID will be automatically mapped to a corresponding Ulid and vice-versa. This works because UUID and Ulid are both represented as 16 byte (128 bit) data struct.
