Section IV - executable

Cargo.toml

daas-reporting.rs

We are now ready to write the executable. To do this, we will working with the following files:

• Cargo.toml (manifest)

• src/bin/daas-reporting.rs (executable)

Tests

To save time on this Workshop, we will skip the create of integrated service tests for this RESTful service.

Code

Declaring the Executable

In the Cargo.toml file, after the that last [[bin]] statement for status_processor, add the following declaration.

[[bin]]
name = "reporting"
path = "src/bin/daas-reporting.rs"

This will tell Cargo that there is a binary file to be compiled and to name the exeutable reporting.

Coding the Executable

Let's begin by creating a file named daas-reporting.rs in the src/bin/ directory.

At the top of the file, we will start be declare the dependent crate with macros and the use statements.

use daas::data_service;
use actix_web::{server};

Lastly, we define the main() function that will be called by the executable.

pub fn main() {    
    std::env::set_var("RUST_LOG", "actix_web=info");
    env_logger::init();

    server::new( || {data_service::service()})
    .bind("127.0.0.1:8001")
    .expect("Can not bind to port 8001")
    .run();
}
