Trait Implementations

impl Clone for Escrow

fn clone(&self) -> Escrow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Escrow

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Escrow

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Escrow

fn eq(&self, other: &Escrow) -> 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 TapMessageBody for Escrow

fn message_type() -> &'static str

Get the message type string for this body type.

fn validate(&self) -> Result<()>

Validate the message body.

fn to_didcomm(&self, from: &str) -> Result<PlainMessage>

Convert this body to a DIDComm message.

fn to_didcomm_with_route<'a, I>( &self, from: &str, to: I, ) -> Result<PlainMessage>

where I: IntoIterator<Item = &'a str>,

Convert this body to a DIDComm message with a custom routing path.

fn from_didcomm(message: &PlainMessage) -> Result<Self>

where Self: Sized,

Extract this body type from a DIDComm message.
