Implementations

impl MT199

pub fn parse_from_block4(block4: &str) -> Result<Self, ParseError>

Parse message from Block 4 content

pub fn parse(input: &str) -> Result<Self, ParseError>

Parse from generic SWIFT input (tries to detect blocks)

pub fn validate_network_rules( &self, _stop_on_first_error: bool, ) -> Vec<SwiftValidationError>

Main validation method - validates all network rules

According to SR 2025 MTn99 specification: “There are no network validated rules for this message type beyond the standard field-specific rules.”

Returns array of validation errors, respects stop_on_first_error flag.

Parameters

• stop_on_first_error: If true, returns immediately upon finding the first error

Returns

• Empty vector (MT199 has no network validation rules)

pub fn is_reject_message(&self) -> bool

Check if this is a reject message

pub fn is_return_message(&self) -> bool

Check if this is a return message

Trait Implementations

impl Clone for MT199

fn clone(&self) -> MT199

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MT199

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MT199

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MT199

fn eq(&self, other: &MT199) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn parse_from_block4(block4: &str) -> Result<Self, ParseError>

Parse message from Block 4 content (fields only)

fn to_mt_string(&self) -> String

Convert to SWIFT MT format (Block 4 content, no wrapper braces)

fn validate_network_rules( &self, stop_on_first_error: bool, ) -> Vec<SwiftValidationError>
