Implementations

impl Event

pub fn extract_principal_ids(&self) -> BTreeSet<&Principal>

Return a set containing all of the Principal IDs involved in an event.

pub fn extract_token_ids(&self) -> BTreeSet<u64>

Return a set containing all of the token ids involved in an event.

pub fn hash(&self) -> EventHash

Compute the hash for the given event.

Trait Implementations

impl AsHashTree for Event

fn root_hash(&self) -> Hash

This method should return the root hash of this hash tree. Must be equivalent to as_hash_tree().reconstruct().

fn as_hash_tree(&self) -> HashTree<'_>

Constructs a hash tree corresponding to the data.

impl CandidType for Event

fn _ty() -> Type

fn id() -> TypeId

fn idl_serialize<__S>(&self, __serializer: __S) -> Result<(), __S::Error>

where __S: Serializer,

fn ty() -> Type

impl Clone for Event

fn clone(&self) -> Event

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Event

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Into<IndefiniteEvent> for Event

fn into(self) -> IndefiniteEvent

Converts this type into the (usually inferred) input type.

impl Serialize for Event

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
