Converts to this type from the input type.

impl<T, S> PartialEq for StorageWeightReclaim<T, S>

where S: PartialEq,

fn eq(&self, __other: &StorageWeightReclaim<T, S>) -> 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.

impl<T, S> TransactionExtension<<T as Config>::RuntimeCall> for StorageWeightReclaim<T, S>

where T: Config + Send + Sync, S: TransactionExtension<<T as Config>::RuntimeCall>, <T as Config>::RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>,

const IDENTIFIER: &'static str = "StorageWeightReclaim<Use `metadata()`!>"

Unique identifier of this signed extension.

type Implicit = <S as TransactionExtension<<T as Config>::RuntimeCall>>::Implicit

Any additional data which was known at the time of transaction construction and can be useful in authenticating the transaction. This is determined dynamically in part from the on-chain environment using the implicit function and not directly contained in the transaction itself and therefore is considered “implicit”.

type Val = (Option<u64>, <S as TransactionExtension<<T as Config>::RuntimeCall>>::Val)

The type that encodes information that can be passed from validate to prepare.

type Pre = (Option<u64>, <S as TransactionExtension<<T as Config>::RuntimeCall>>::Pre)

The type that encodes information that can be passed from prepare to post_dispatch.

fn implicit( &self, ) -> Result<<StorageWeightReclaim<T, S> as TransactionExtension<<T as Config>::RuntimeCall>>::Implicit, TransactionValidityError>

Determine any additional data which was known at the time of transaction construction and can be useful in authenticating the transaction. The expected usage of this is to include in any data which is signed and verified as part of transaction validation. Also perform any pre-signature-verification checks and return an error if needed.

fn metadata() -> Vec<TransactionExtensionMetadata>

Returns the metadata for this extension.

fn weight(&self, call: &<T as Config>::RuntimeCall) -> Weight

The weight consumed by executing this extension instance fully during transaction dispatch.
