Struct pretty_exec::clap::builder::RangedI64ValueParser

[−]

pub struct RangedI64ValueParser<T = i64> where
    T: TryFrom<i64> + Clone + Send + Sync, { /* private fields */ }

Expand description

Parse number that fall within a range of values

Example

Usage:

let mut cmd = clap::Command::new("raw")
    .arg(
        clap::Arg::new("port")
            .long("port")
            .value_parser(clap::value_parser!(u16).range(3000..))
            .takes_value(true)
            .required(true)
    );

let m = cmd.try_get_matches_from_mut(["cmd", "--port", "3001"]).unwrap();
let port: u16 = *m.get_one("port")
    .expect("required");
assert_eq!(port, 3001);

Semantics:

let value_parser = clap::builder::RangedI64ValueParser::<i32>::new().range(-1..200);
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("random")).is_err());
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("")).is_err());
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("-200")).is_err());
assert!(value_parser.parse_ref(&cmd, arg, OsStr::new("300")).is_err());
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("-1")).unwrap(), -1);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("0")).unwrap(), 0);
assert_eq!(value_parser.parse_ref(&cmd, arg, OsStr::new("50")).unwrap(), 50);
