Trait Implementations

impl Clone for Field20

fn clone(&self) -> Field20

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field20

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Field20

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Field20

fn eq(&self, other: &Field20) -> 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 serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SwiftField for Field20

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

where Self: Sized,

Parse field from SWIFT format (without :TAG: prefix)

fn to_swift_string(&self) -> String

Convert to SWIFT format (includes :TAG: prefix)

fn parse_with_variant( value: &str, _variant: Option<&str>, _field_tag: Option<&str>, ) -> Result<Self>

where Self: Sized,

Parse field with variant (e.g., 50A, 50K) for enum fields

fn get_variant_tag(&self) -> Option<&'static str>

Get variant tag (e.g., “A”, “K”) for enum fields, None for simple fields
