Struct diem_types::event::EventHandle

pub struct EventHandle { /* fields omitted */ }

A Rust representation of an Event Handle Resource.

Implementations

impl EventHandle

pub fn new(key: EventKey, count: u64) -> Self

Constructs a new Event Handle

pub fn key(&self) -> &EventKey

Return the key to where this event is stored in EventStore.

pub fn count(&self) -> u64

Return the counter for the handle

pub fn count_mut(&mut self) -> &mut u64

pub fn random_handle(count: u64) -> Self

Create a random event handle for testing

pub fn new_from_address(addr: &AccountAddress, salt: u64) -> Self

Derive a unique handle by using an AccountAddress and a counter.

impl EventHandle

pub fn strategy_impl(
    event_key_strategy: impl Strategy<Value = EventKey>
) -> impl Strategy<Value = Self>

Trait Implementations

impl Arbitrary for EventHandle

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<Self>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_args: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for EventHandle

fn clone(&self) -> EventHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EventHandle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventHandle

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

Deserialize this value from the given Serde deserializer.

impl PartialEq<EventHandle> for EventHandle

fn eq(&self, other: &EventHandle) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &EventHandle) -> bool

This method tests for !=.

impl Serialize for EventHandle

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

Serialize this value into the given Serde serializer.
