pub enum DocumentEvent {
    Transfer {
        to_identity_id: Identifier,
    },
    Purchase {

        price: Credits,
    },
    PriceUpdate {
        price: Credits,
    },
}

Implementations

impl DocumentEvent

pub fn associated_document_type_name(&self) -> &'static str

The name of the document type in the document history contract that records this event.

pub fn associated_document_type<'a>( &self, document_history_contract: &'a DataContract, ) -> Result<DocumentTypeRef<'a>, ProtocolError>

The document type in the document history contract that records this event.

pub fn build_historical_document_owned( self, source_data_contract_id: Identifier, source_document_type_name: &str, source_document_id: Identifier, owner_id: Identifier, owner_nonce: IdentityNonce, block_info: &BlockInfo, ) -> Document

Builds the history document recording this event.

The id is deterministically derived from the source document, the acting identity and its contract nonce, so every validator produces the same history document for the same state transition.

Trait Implementations

impl Clone for DocumentEvent

fn clone(&self) -> DocumentEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DocumentEvent

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

Formats the value using the given formatter.

impl Eq for DocumentEvent

impl PartialEq for DocumentEvent

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