where PhantomData<Runtime>: Encode,

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

where __CodecOutputEdqy: Output + ?Sized,

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

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

impl<Runtime> PartialEq for BalanceTransferCheckExtension<Runtime>

where Runtime: PartialEq,

impl<Runtime> TransactionExtension<<Runtime as Config>::RuntimeCall> for BalanceTransferCheckExtension<Runtime>

where Runtime: Config + Config + TypeInfo + Debug + Send + Sync + BalanceTransferChecks, <<Runtime as Config>::RuntimeCall as Dispatchable>::RuntimeOrigin: AsSystemOriginSigner<<Runtime as Config>::AccountId> + Clone, <Runtime as Config>::RuntimeCall: MaybeBalancesCall<Runtime> + MaybeNestedCall<Runtime>,

const IDENTIFIER: &'static str = "BalanceTransferCheckExtension"

Unique identifier of this signed extension.

type 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 = Val

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

type Pre = Pre

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

fn weight(&self, _call: &<Runtime as Config>::RuntimeCall) -> Weight

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

fn validate( &self, origin: <Runtime as Config>::RuntimeOrigin, call: &<Runtime as Config>::RuntimeCall, _info: &<<Runtime as Config>::RuntimeCall as Dispatchable>::Info, _len: usize, _self_implicit: <BalanceTransferCheckExtension<Runtime> as TransactionExtension<<Runtime as Config>::RuntimeCall>>::Implicit, _inherited_implication: &impl Encode, _source: TransactionSource, ) -> Result<(ValidTransaction, <BalanceTransferCheckExtension<Runtime> as TransactionExtension<<Runtime as Config>::RuntimeCall>>::Val, <<Runtime as Config>::RuntimeCall as Dispatchable>::RuntimeOrigin), TransactionValidityError>

Validate a transaction for the transaction queue.

fn prepare( self, val: <BalanceTransferCheckExtension<Runtime> as TransactionExtension<<Runtime as Config>::RuntimeCall>>::Val, _origin: &<<Runtime as Config>::RuntimeCall as Dispatchable>::RuntimeOrigin, _call: &<Runtime as Config>::RuntimeCall, _info: &<<Runtime as Config>::RuntimeCall as Dispatchable>::Info, _len: usize, ) -> Result<<BalanceTransferCheckExtension<Runtime> as TransactionExtension<<Runtime as Config>::RuntimeCall>>::Pre, TransactionValidityError>

Do any pre-flight stuff for a transaction after validation.

fn post_dispatch_details( pre: <BalanceTransferCheckExtension<Runtime> as TransactionExtension<<Runtime as Config>::RuntimeCall>>::Pre, _info: &<<Runtime as Config>::RuntimeCall as Dispatchable>::Info, _post_info: &<<Runtime as Config>::RuntimeCall as Dispatchable>::PostInfo, _len: usize, _result: &Result<(), DispatchError>, ) -> Result<Weight, TransactionValidityError>

Do any post-flight stuff for an extrinsic.

fn implicit(&self) -> Result<Self::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 post_dispatch( pre: Self::Pre, info: &<Call as Dispatchable>::Info, post_info: &mut <Call as Dispatchable>::PostInfo, len: usize, result: &Result<(), DispatchError>, ) -> Result<(), TransactionValidityError>

A wrapper for post_dispatch_details that refunds the unspent weight consumed by this extension into the post dispatch information.

fn bare_validate( _call: &Call, _info: &<Call as Dispatchable>::Info, _len: usize, ) -> Result<ValidTransaction, TransactionValidityError>

Validation logic for bare extrinsics.

fn bare_validate_and_prepare( _call: &Call, _info: &<Call as Dispatchable>::Info, _len: usize, ) -> Result<(), TransactionValidityError>

All pre-flight logic run before dispatching bare extrinsics.

fn bare_post_dispatch( _info: &<Call as Dispatchable>::Info, _post_info: &mut <Call as Dispatchable>::PostInfo, _len: usize, _result: &Result<(), DispatchError>, ) -> Result<(), TransactionValidityError>

Post dispatch logic run after dispatching bare extrinsics.

impl<Runtime> TypeInfo for BalanceTransferCheckExtension<Runtime>

where PhantomData<Runtime>: TypeInfo + 'static, Runtime: TypeInfo + 'static,

type Identity = BalanceTransferCheckExtension<Runtime>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
