Trait Implementations

impl<E: Clone + Parameter + Member, T: Clone> Clone for EventRecord<E, T>

fn clone(&self) -> EventRecord<E, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E, T> Debug for EventRecord<E, T>where E: Debug + Parameter + Member, T: Debug,

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

Formats the value using the given formatter.

impl<E, T> Decode for EventRecord<E, T>where E: Decode + Parameter + Member, Vec<T>: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self> ) -> Result<DecodeFinished, Error>where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl<E, T> Encode for EventRecord<E, T>where E: Encode + Parameter + Member, Vec<T>: Encode,

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8, Global>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> Rwhere F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<E: PartialEq + Parameter + Member, T: PartialEq> PartialEq<EventRecord<E, T>> for EventRecord<E, T>

fn eq(&self, other: &EventRecord<E, T>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<E, T> Serialize for EventRecord<E, T>where E: Serialize + Parameter + Member, T: Serialize,

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

Serialize this value into the given Serde serializer.

impl<E, T> TypeInfo for EventRecord<E, T>where E: TypeInfo + 'static + Parameter + Member, Vec<T>: TypeInfo + 'static, T: TypeInfo + 'static,

type Identity = EventRecord<E, T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<E, T> EncodeLike<EventRecord<E, T>> for EventRecord<E, T>where E: Encode + Parameter + Member, Vec<T>: Encode,

impl<E: Eq + Parameter + Member, T: Eq> Eq for EventRecord<E, T>

impl<E: Parameter + Member, T> StructuralEq for EventRecord<E, T>

impl<E: Parameter + Member, T> StructuralPartialEq for EventRecord<E, T>
