To calculate the Rate of Change (ROC) using Rust, you can follow these steps:

- First, import the necessary libraries by adding the following lines to your Rust code:

```
1
``` |
use std::cmp::{PartialEq, PartialOrd}; |

**Define a function that will calculate the ROC. This function should take two parameters**: the initial value and the final value. The ROC can be calculated using the formula:

[ ROC = rac{(final - initial)}{initial} * 100 ]

Here's an example function in Rust:

1 2 3 |
fn calculate_roc(initial: f64, final: f64) -> f64 { ((final - initial) / initial) * 100.0 } |

- Call the calculate_roc function with the initial and final values as arguments to calculate the ROC. For example:

1 2 3 4 5 6 7 8 |
fn main() { let initial_value = 50.0; let final_value = 70.0; let roc = calculate_roc(initial_value, final_value); println!("The Rate of Change (ROC) is: {:.2}%", roc); } |

- Compile and run your Rust code to see the calculated ROC value. The output should display the ROC percentage.

That's it! You have successfully calculated the Rate of Change using Rust.
