impl FromStr for Range

fn from_str(s: &str) -> Result<Self, &'static str>

Parse a string of the form a-b into a Range

use std::str::FromStr;
use uucore::ranges::Range;
assert_eq!(Range::from_str("5"), Ok(Range { low: 5, high: 5 }));
assert_eq!(Range::from_str("4-"), Ok(Range { low: 4, high: usize::MAX - 1 }));
assert_eq!(Range::from_str("-4"), Ok(Range { low: 1, high: 4 }));
assert_eq!(Range::from_str("2-4"), Ok(Range { low: 2, high: 4 }));
assert!(Range::from_str("0-4").is_err());
assert!(Range::from_str("4-2").is_err());
assert!(Range::from_str("-").is_err());
assert!(Range::from_str("a").is_err());

impl PartialEq for Range

fn eq(&self, other: &Range) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
