Function konst::primitive::parse_bool

pub const fn parse_bool(s: &str) -> Result<bool, ParseBoolError>

Parses a bool from a &str.

This returns an Err if the string would not successfully .parse() into a bool.

To parse a bool from only part of a string, you can use Parser::parse_bool.

Example

use konst::{
    primitive::{ParseBoolResult, parse_bool},
    unwrap_ctx,
};

const T: ParseBoolResult = parse_bool("true");
const F: ParseBoolResult = parse_bool("false");

assert_eq!(T, Ok(true));
assert_eq!(F, Ok(false));

// This is how you can unwrap bools parsed from strings, at compile-time.
const T2: bool = unwrap_ctx!(parse_bool("true"));
const F2: bool = unwrap_ctx!(parse_bool("false"));

assert_eq!(T2, true);
assert_eq!(F2, false);

assert!(parse_bool("0").is_err());
assert!(parse_bool("FALSE").is_err());
