[−][src]Trait range_check::Check

pub trait Check<R: RangeBounds<Self>>: Sized + PartialOrd + Copy {
    fn check_range(self, range: R) -> Result<Self, OutOfRangeError<Self>>;
}

Trait that provides early returns for failed range checks using the Result type.

Required methods

`fn check_range(self, range: R) -> Result<Self, OutOfRangeError<Self>>`

Checks whether self is within the given range. If it is, re-returns self. Otherwise, returns an Error that contains both the value and the range.

Examples

use range_check::Check;

assert!(24680.check_range(1..99999).is_ok());
assert!(24680.check_range(1..9999).is_err());
