refinery

Pros of Diesel

• More mature and widely adopted ORM with a larger ecosystem
• Provides a powerful query builder and type-safe SQL abstractions
• Supports multiple database backends (PostgreSQL, MySQL, SQLite)

Cons of Diesel

• Steeper learning curve due to its more complex API
• Requires macro-heavy code, which can be harder to debug
• Slower compile times due to extensive macro usage

Code Comparison

Diesel migration:

diesel::migration_macros::embed_migrations!();

fn run_migrations(conn: &PgConnection) {
    embedded_migrations::run(conn).unwrap();
}

Refinery migration:

let migration = refinery::Migration::new("V1__create_users_table")
    .with_sql(include_str!("./migrations/V1__create_users_table.sql"));
let mut runner = Runner::new(&[migration]);
runner.run(&mut conn)?;

Refinery focuses on simplicity and ease of use for database migrations, while Diesel provides a more comprehensive ORM solution with additional features. Refinery allows for more straightforward migration management without the need for complex macros, making it easier to get started with and maintain. However, Diesel offers more advanced querying capabilities and broader database support, making it suitable for larger and more complex projects.

Pros of SQLx

• Supports async/await and multiple database backends (PostgreSQL, MySQL, SQLite)
• Provides compile-time checked queries, ensuring type safety
• Offers a rich set of features, including connection pooling and migrations

Cons of SQLx

• Steeper learning curve due to its extensive feature set
• Requires macros for compile-time query checking, which can be complex for beginners
• Larger dependency footprint compared to Refinery

Code Comparison

SQLx:

let pool = SqlitePool::connect("sqlite::memory:").await?;
let row: (i64,) = sqlx::query_as("SELECT $1")
    .bind(150_i64)
    .fetch_one(&pool).await?;

Refinery:

let mut conn = Connection::open_in_memory()?;
let migration = Migration::new("CREATE TABLE users (id INTEGER PRIMARY KEY)");
Runner::new(&[migration])
    .run(&mut conn)?;

Summary

SQLx is a feature-rich, async-first database library with compile-time query checking, supporting multiple backends. Refinery focuses primarily on database migrations with a simpler API. SQLx offers more comprehensive database interaction capabilities but comes with a steeper learning curve, while Refinery provides a straightforward solution for managing database schema changes.

Pros of sea-orm

• Full-featured ORM with entity generation, query building, and migrations
• Supports multiple database backends (MySQL, PostgreSQL, SQLite)
• Active development with frequent updates and community support

Cons of sea-orm

• Steeper learning curve due to more complex API and features
• Potentially higher overhead for simple database operations
• Requires more boilerplate code for basic CRUD operations

Code Comparison

sea-orm example:

let post: Option<post::Model> = Post::find_by_id(1).one(&db).await?;
let comments: Vec<comment::Model> = post.find_related(Comment).all(&db).await?;

refinery example:

let migration = Migration::new("V1__create_users_table")
    .with_up("CREATE TABLE users (id INTEGER PRIMARY KEY)");
runner.run(&[migration])?;

Summary

sea-orm is a comprehensive ORM solution with more features and flexibility, while refinery focuses specifically on database migrations. sea-orm offers a higher-level abstraction for database operations but may introduce more complexity. refinery provides a simpler approach to managing database schema changes but lacks the full ORM capabilities of sea-orm.

Pros of rust-postgres

• More comprehensive PostgreSQL driver with full-featured API
• Supports asynchronous operations with tokio
• Extensive documentation and examples

Cons of rust-postgres

• Focused solely on PostgreSQL, not a general-purpose database migration tool
• Steeper learning curve for basic database operations

Code Comparison

rust-postgres:

let mut client = Client::connect("host=localhost user=postgres", NoTls)?;
let rows = client.query("SELECT $1::TEXT", &[&"Hello, World!"])?;
let value: &str = rows[0].get(0);

refinery:

let migration = Migration::new("V1__create_users_table")
    .with_up("CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT NOT NULL)")
    .with_down("DROP TABLE users");
runner.run(&[migration])?;

Key Differences

• refinery is a database migration tool supporting multiple databases, while rust-postgres is a PostgreSQL-specific driver
• rust-postgres offers more low-level control and advanced PostgreSQL features
• refinery provides a higher-level abstraction for managing database schema changes

Use Cases

• Choose refinery for managing database migrations across different database systems
• Opt for rust-postgres when building PostgreSQL-specific applications requiring advanced features and fine-grained control

Pros of Prisma Engines

• More comprehensive database tooling, including query engine and migration engine
• Supports multiple databases (PostgreSQL, MySQL, SQLite, SQL Server)
• Active development with frequent updates and improvements

Cons of Prisma Engines

• Larger and more complex codebase, potentially harder to contribute to
• Tightly coupled with the Prisma ecosystem, less flexible for standalone use
• Steeper learning curve due to its extensive feature set

Code Comparison

Refinery migration:

V1__create_users_table {
    fn up(&self) -> String {
        "CREATE TABLE users (
            id SERIAL PRIMARY KEY,
            name VARCHAR NOT NULL
        )".to_string()
    }
}

Prisma Engines migration:

model User {
  id   Int    @id @default(autoincrement())
  name String
}

Key Differences

• Refinery focuses solely on database migrations, while Prisma Engines provides a broader set of database-related tools
• Refinery uses raw SQL for migrations, whereas Prisma Engines uses a declarative schema language
• Prisma Engines is part of a larger ORM ecosystem, while Refinery is a standalone migration tool

Use Cases

• Choose Refinery for lightweight, SQL-based migrations in Rust projects
• Opt for Prisma Engines when building applications with the Prisma ORM and requiring a full-featured database toolkit

Pros of rbatis

• More comprehensive ORM functionality, including CRUD operations and query building
• Supports multiple database backends (MySQL, PostgreSQL, SQLite)
• Provides async support out of the box

Cons of rbatis

• Steeper learning curve due to more complex API
• Heavier dependency footprint
• May introduce more overhead for simple database operations

Code Comparison

rbatis:

#[crud_table]
#[derive(Clone, Debug)]
pub struct User {
    pub id: Option<i32>,
    pub name: String,
}

let user = User { id: None, name: "John".to_string() };
rb.save(&user, &[]).await?;

refinery:

#[derive(Queryable)]
pub struct User {
    pub id: i32,
    pub name: String,
}

diesel::insert_into(users::table)
    .values(&NewUser { name: "John" })
    .execute(conn)?;

Summary

rbatis offers a more feature-rich ORM experience with support for multiple databases and async operations, while refinery focuses on database migrations and schema management. rbatis may be better suited for complex applications with diverse database needs, whereas refinery provides a simpler, more focused solution for managing database schemas and migrations in Rust projects.
