Struct SwiftParser 

pub struct SwiftParser { /* private fields */ }

Main parser for SWIFT MT messages

Purpose

Primary parsing engine that converts raw SWIFT message strings into typed, validated message structures. Handles all aspects of SWIFT message processing including block extraction, header parsing, field parsing, and type-safe message construction.

Capabilities

• Multi-Message Support: Parses all 24 supported MT message types
• Flexible Parsing: Both type-specific and auto-detection parsing modes
• Robust Error Handling: Comprehensive error reporting for malformed messages
• Field Validation: Format validation and business rule checking
• Position Tracking: Maintains field order for sequential processing requirements

Parsing Process

1. Block Extraction: Identifies and extracts SWIFT blocks 1-5
2. Header Validation: Parses and validates basic, application, user headers and trailer
3. Message Type Detection: Determines message type from application header
4. Field Processing: Parses block 4 fields with position and variant tracking
5. Type Construction: Builds strongly-typed message structures
6. Validation: Applies format and business rule validation

Thread Safety

SwiftParser is stateless and thread-safe. All methods are static and can be called concurrently from multiple threads.

Implementations

impl SwiftParser

pub fn new() -> Self

Create a new parser with default configuration

pub fn with_config(config: ParserConfig) -> Self

Create a new parser with custom configuration

pub fn parse_with_errors<T: SwiftMessageBody>( &self, raw_message: &str, ) -> Result<ParseResult<SwiftMessage<T>>>

Parse a message and return ParseResult with all errors collected

pub fn parse<T: SwiftMessageBody>(raw_message: &str) -> Result<SwiftMessage<T>>

Parse a raw SWIFT message string into a typed message (static method for backward compatibility)

pub fn parse_message<T: SwiftMessageBody>( &self, raw_message: &str, ) -> Result<SwiftMessage<T>>

Parse a raw SWIFT message string into a typed message with configuration support

pub fn parse_auto(raw_message: &str) -> Result<ParsedSwiftMessage>

Parse a raw SWIFT message string with automatic message type detection (static method for backward compatibility)

pub fn parse_message_auto( &self, raw_message: &str, ) -> Result<ParsedSwiftMessage>

Parse a raw SWIFT message string with automatic message type detection and configuration support

pub fn extract_block( raw_message: &str, block_index: u8, ) -> Result<Option<String>>

Extract a specific message block from raw SWIFT message with SWIFT validation

Trait Implementations

impl Default for SwiftParser

fn default() -> Self

Returns the “default value” for a type.
