[−][src]Function extended_fizzbuzz::fizzbuzz
pub fn fizzbuzz(
from: usize,
to: usize,
matchers: &Vec<Matcher>
) -> Result<(), FizzBuzzError>
Provides a configurable version of FizzBuzz.
Parameters
With from
and to
you can define the number area for which to run the operation. Both of
these values are inclusive. This means that if you specify 1 and 10, the numbers for which
output is produced are: 1,2,3,4,5,6,7,8,9,10
With matchers
you can provide some matcher::Matcher
s. These are used to configure how
numbers are substituted with words. The matchers are tested in the order of the vector.
Errors
- Returns
FizzBuzzError::FromBiggerThanTo
, if thefrom
parameters value is bigger than theto
parameters value.
Example
use extended_fizzbuzz::{fizzbuzz, Matcher}; let matchers = vec![ Matcher::new(3, "Fizz").unwrap(), Matcher::new(5, "Buzz").unwrap(), ]; assert!(fizzbuzz(1, 10, &matchers).is_ok()); assert!(fizzbuzz(10, 1, &matchers).is_err());
