Diesel - A safe, extensible ORM and Query Builder for Rust

•    Rust

Diesel is the most productive way to interact with databases in Rust because of its safe and composable abstractions over queries. Diesel offers a high level query builder and lets you think about your problems in Rust, not SQL. Its focus on zero-cost abstractions allows Diesel to run your query and load your data even faster than C. Unlike Active Record and other ORMs, Diesel is designed to be abstracted over. Diesel enables you to write reusable code and think in terms of your problem domain and not SQL.

beedb - beedb is a go ORM,support database/sql interface，pq/mysql/sqlite

•    Go

Beedb is an ORM for Go. It lets you map Go structs to tables in a database. It's intended to be very lightweight, doing very little beyond what you really want. For example, when fetching data, instead of re-inventing a query syntax, we just delegate your query to the underlying database, so you can write the "where" clause of your SQL statements directly. This allows you to have more flexibility while giving you a convenience layer. But beedb also has some smart defaults, for those times when complex queries aren't necessary.Relationship-support is not implemented, for this we will recommend you to use Beego.orm.
