In this chapter, we will create a RESTful API web service using open source crates in the Rust language. The simple RESTful API in Rust will connect to a MongoDB service, which provides an end-to-end API solution.

We will look at how to perform GET, POST, and DELETE requests on user data from an endpoint. The crates, nickel.rs and the MongoDB Rust driver, make it possible to create these actions in the Rust language.
