Module error 

Error types for mathlex parsing operations.

This module defines comprehensive error types for reporting parsing failures, including precise location information and helpful error messages.

Error Architecture

• Position: A point in source text (line, column, offset)
• Span: A range in source text (start and end positions)
• ParseErrorKind: The specific type of parsing error
• ParseError: Complete error with kind, location, and context
• ParseResult<T>: Standard Result type for parsing operations

Example

use mathlex::error::{Position, Span, ParseError, ParseErrorKind};

let pos = Position::new(1, 5, 5);
let error = ParseError::new(
    ParseErrorKind::UnexpectedEof {
        expected: vec!["number".to_string()],
    },
    Some(Span::new(pos, pos)),
);

assert_eq!(error.to_string(), "unexpected end of input, expected number at 1:5");
