Struct timestamp::CleanUpTimestamp

pub struct CleanUpTimestamp<T>(/* private fields */);

Allows users to voluntarily clean up old timestamps by showing that there exists another timestamp that is at least the CLEANUP_AGE newer.

You can clean up multiple timestamps at once, but you only peek at a single new reference. Although it is useless to do so, it is valid for a transaction to clean up zero timestamps.

Trait Implementations

impl<T> Clone for CleanUpTimestamp<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for CleanUpTimestamp<T>

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

Formats the value using the given formatter.

impl<T> Decode for CleanUpTimestamp<T>

where PhantomData<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<T> Default for CleanUpTimestamp<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for CleanUpTimestamp<T>

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> Encode for CleanUpTimestamp<T>

where PhantomData<T>: 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<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback ) -> __CodecOutputReturn

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

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<T: PartialEq> PartialEq for CleanUpTimestamp<T>

fn eq(&self, other: &CleanUpTimestamp<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<T> Serialize for CleanUpTimestamp<T>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: TimestampConfig> SimpleConstraintChecker for CleanUpTimestamp<T>

type Error = TimestampError

The error type that this constraint checker may return

fn check( &self, input_data: &[DynamicallyTypedData], evicted_input_data: &[DynamicallyTypedData], peek_data: &[DynamicallyTypedData], output_data: &[DynamicallyTypedData] ) -> Result<TransactionPriority, Self::Error>

The on chain logic that makes the final check for whether a transaction is valid.

impl<T> TypeInfo for CleanUpTimestamp<T>

where PhantomData<T>: TypeInfo + 'static, T: TypeInfo + 'static,

type Identity = CleanUpTimestamp<T>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.

impl<T> EncodeLike for CleanUpTimestamp<T>

where PhantomData<T>: Encode,

impl<T: Eq> Eq for CleanUpTimestamp<T>
