Percentage

percentage 是一个库，旨在以更安全和更易于调试的方式使用百分比。每当您看到百分比时，您就会知道正在计算什么，而无需修改代码。

示例

// 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'
