impl ValueRange

fn new<impl Into<Self>: Into<Self>>(range: impl Into<Self>) -> Self

Create a range

Panics

If the end is less than the start (debug builds)

Examples

# use clap_builder as clap;
# use clap::builder::ValueRange;
let range = ValueRange::new(5);
let range = ValueRange::new(5..10);
let range = ValueRange::new(5..=10);
let range = ValueRange::new(5..);
let range = ValueRange::new(..10);
let range = ValueRange::new(..=10);

While this will panic:

# use clap_builder as clap;
# use clap::builder::ValueRange;
let range = ValueRange::new(10..5);  // Panics!

fn min_values(self: &Self) -> usize

Fewest number of values the argument accepts

fn max_values(self: &Self) -> usize

Most number of values the argument accepts

fn takes_values(self: &Self) -> bool

Report whether the argument takes any values (ie is a flag)

Examples

# use clap_builder as clap;
# use clap::builder::ValueRange;
let range = ValueRange::new(5);
assert!(range.takes_values());

let range = ValueRange::new(0);
assert!(!range.takes_values());
