[−][src]Crate percentage
Percentage
percentage
is a crate trying to make using percentages in a safer way and easier to debug.
Whenever you see a Percentage, you will know what is being calculated, instead of having to revise the code.
Example
// You only need to import the `Percentage` struct use percentage::Percentage; // Here we create the percentage to apply let percent = Percentage::from(50); println!("{}", percent.value()); // Will print '50' // We can apply the percent to any number we want assert_eq!(15, percent.apply_to(30)); println!("50% of 30 is: {}", percent.apply_to(30)); // Will print '50% of 30 is: 15' // If you need to use floating points for the percent, you can use `from_decimal` instead let percent = Percentage::from_decimal(0.5); assert_eq!(15.0, percent.apply_to(30.0)); println!("50% of 30.0 is: {}", percent.apply_to(30.0)); // Will print '50% of 30.0 is: 15.0'
