Crate swift_mt_message 

SWIFT MT Message Parser

Rust library for parsing, validating, and generating SWIFT MT financial messages.

Features

• Type-safe parsing with dedicated field structures
• SWIFT validation with 1,335 error codes (T/C/D/E/G series)
• Sample generation with configurable scenarios
• JSON serialization with clean flattened output
• 30+ message types (MT101-MT950)

Quick Start

use swift_mt_message::parser::SwiftParser;

let message = "{1:F01BANKDEFFAXXX0000000000}{2:I103BANKDEFFAXXXU3003}{4:\r\n:20:REF123\r\n:23B:CRED\r\n:32A:240719USD1234,56\r\n:50K:/12345678\r\nJOHN DOE\r\n:59:/98765432\r\nJANE SMITH\r\n:71A:OUR\r\n-}";
let parsed = SwiftParser::parse_auto(message)?;
