Section #14 coding challenge

For this challenge, we'll be modeling a fitness program.

Create a new Cargo project. Give your project a name of fitness.

The project will include both a binary crate and a library crate. Create the required files in the src directory.

We'll have 3 modules: diet, weightlifting, and cardio. Declare the 3 modules in the library crate root.

Use an inline module definition for the diet module. Inside the diet module:

  • Declare a NUTRITIONIST constant set to "Norah Nutrition"

  • Declare an ask_about_program function that outputs the text "The nutritionist is Norah Nutrition" (use the constant).

Use a file module definition for the weightlifting module. Inside the weightlifting module:

  • Declare a PERSONAL_TRAINER constant set to "Will Weight"

  • Declare an ask_about_program function that outputs the text "The weightlifting trainer is Will Weight" (use the constant)

  • Declare an Exercise struct with a name field (String) and a reps field (u32). Derive a Debug implementation.

  • Add a new constructor function to the Exercise struct that returns an Exercise instance.

Use a folder module definition for the cardio module. Inside the cardio module:

  • Declare a PERSONAL_TRAINER constant set to "Carl Cardio"

  • Declare an ask_about_program function that outputs the text "The cardio trainer is Carl Cardio" (use the constant)

  • Declare a CardioTool enum with 2 variants: Treadmill and Bike. Derive a Debug implementation.

  • Declare an Exercise struct with a day field (String), a tool field (CardioTool), and a minutes field (u32). Derive a Debug implementation.

  • Add a new constructor function to the Exercise struct that returns an Exercise instance.

In the library crate root:

  • Use the use keyword to bring the CardioTool enum into scope

  • Assign the alias CardioExercise to cardio::Exercise

  • Assign the alias WeightliftingExercise to weightlifting::Exercise

  • Define a GymWorkout struct with a cardio field (an Exercise struct from the cardio module) and a weightlifting field (an Exercise struct from the weightlifting module). Implement the Debug trait. //tbd

  • Define a new constructor function on the GymWorkout struct. The function should invoke ALL 3 of the ask_about_program functions, then return an instance of the GymWorkout struct. Pick arbitrary values for the required struct fields.

Finally, in the binary crate root:

  • Invoke the GymWorkout::new function and print out the GymWorkout struct in Debug format.

Here is what a sample output might look like:

The nutritionist is Norah Nutrition The cardio trainer is Carl Cardio The weightlifting trainer is Will Weight GymWorkout { weightlifting: Exercise { name: "Bench Press", reps: 8, }, cardio: Exercise { day: "Thursday", tool: Bike, minutes: 30, }, }
