Module error 

Error types with source location tracking.

All errors in logicaffeine carry a Span indicating where in the source text the error occurred. This enables precise, contextual error messages.

Example

use logicaffeine_base::{SpannedError, Span, Result};

fn parse_number(s: &str) -> Result<i32> {
    s.parse().map_err(|_| SpannedError::new(
        format!("invalid number: '{}'", s),
        Span::new(0, s.len()),
    ))
}

let err = parse_number("abc").unwrap_err();
assert!(err.to_string().contains("invalid number"));
