Error Handling

Comprehensive error types for SWIFT MT message parsing and validation.

Error Types

• ParseError: Message parsing and field extraction failures
• ValidationError: Field format and business rule violations
• SwiftValidationError: SWIFT network validation (1,335 error codes: T/C/D/E/G series)

Example

use swift_mt_message::parser::SwiftParser;
use swift_mt_message::ParseError;

match SwiftParser::parse_auto(msg) {
    Ok(message) => println!("Success"),
    Err(ParseError::InvalidFieldFormat(err)) => {
        eprintln!("Field {}: {}", err.field_tag, err.component_name);
    },
    Err(other) => eprintln!("{}", other),
}
