In Module II, we build out a RESTful service that responded with "Hello World!" whenever a GET call was made to the service. The coding of this service was comprised of 3 basic parts.

  1. Declarations of dependent, (e.g.: Crates.toml, extern crate and use)

  2. Constructing the module, (e.g.: src/hello_world.rs)

  3. Constructing the executable service, (e.g.: src/bin/hello-world.rs)

We will follow the same pattern for building out this RESTful service for sourcing data to our reporting system.

Let beginning with declaring our dependencies. Because we will be implementing Basic Authentication, we will need to include the actix-web-httpauth crate that extends the actix-web package. This should be declared in the [dependencies] section of the Cargo.toml file

actix-web-httpauth = "0.1.0"

Now is a good time to rerun the cargo test command to ensure all your tests still pass.

Cargo.toml
