Variants

Updated

A Parameter was set.

Is also emitted when the value was not changed.

Fields

key: <T::RuntimeParameters as AggregatedKeyValue>::Key

old_value: Option<<T::RuntimeParameters as AggregatedKeyValue>::Value>

The old value before this call.

new_value: Option<<T::RuntimeParameters as AggregatedKeyValue>::Value>

The new value after this call.

Trait Implementations

impl<T: Config> Clone for Event<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Config> Debug for Event<T>

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

Formats the value using the given formatter.

impl<T: Config> Decode for Event<T>

where <T::RuntimeParameters as AggregatedKeyValue>::Key: Decode, Option<<T::RuntimeParameters as AggregatedKeyValue>::Value>: 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<T: Config> Encode for Event<T>

where <T::RuntimeParameters as AggregatedKeyValue>::Key: Encode, Option<<T::RuntimeParameters as AggregatedKeyValue>::Value>: Encode,

fn size_hint(&self) -> usize

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

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

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

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

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where 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<T: Config> From<Event<T>> for ()

fn from(_: Event<T>)

Converts to this type from the input type.

impl<T: Config> PartialEq for Event<T>

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