Struct ProtocolExtensionEnvelope 

pub struct ProtocolExtensionEnvelope {
    pub protocol: ProtocolDescriptor,
    pub fields: Map<String, Value>,
    pub evidence_refs: Vec<EvidenceReference>,
}

Available on crate feature payments only.

Lossless protocol-specific fields preserved alongside canonical state.

Fields

protocol: ProtocolDescriptor

fields: Map<String, Value>

evidence_refs: Vec<EvidenceReference>

Implementations

impl ProtocolExtensionEnvelope

pub fn new(protocol: ProtocolDescriptor) -> ProtocolExtensionEnvelope

Creates an empty extension envelope for one protocol source.

pub fn with_field( self, key: impl Into<String>, value: Value, ) -> ProtocolExtensionEnvelope

Appends one raw protocol field without discarding its original shape.

pub fn with_evidence_ref( self, evidence_ref: EvidenceReference, ) -> ProtocolExtensionEnvelope

Appends one evidence reference associated with the extension envelope.

pub fn is_empty(&self) -> bool

Returns true when the envelope carries neither fields nor evidence references.

Trait Implementations

impl Clone for ProtocolExtensionEnvelope

fn clone(&self) -> ProtocolExtensionEnvelope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProtocolExtensionEnvelope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ProtocolExtensionEnvelope

fn deserialize<__D>( __deserializer: __D, ) -> Result<ProtocolExtensionEnvelope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ProtocolExtensionEnvelope

fn eq(&self, other: &ProtocolExtensionEnvelope) -> 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.

impl Serialize for ProtocolExtensionEnvelope

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
