Struct pallet_asset_conversion_tx_payment::ChargeAssetTxPayment

pub struct ChargeAssetTxPayment<T: Config> { /* private fields */ }

Require payment for transaction inclusion and optionally include a tip to gain additional priority in the queue.

Wraps the transaction logic in [pallet_transaction_payment] and extends it with assets. An asset ID of None falls back to the underlying transaction payment logic via the native currency.

Transaction payments are processed using different handlers based on the asset type:

• Payments with a native asset are charged by [pallet_transaction_payment::Config::OnChargeTransaction].
• Payments with other assets are charged by Config::OnChargeAssetTransaction.

impl<T: Config> Encode for ChargeAssetTxPayment<T>

where Option<T::AssetId>: Encode, <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance: HasCompact,

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>

Calculates the encoded size.

impl<T: PartialEq + Config> PartialEq for ChargeAssetTxPayment<T>

where T::AssetId: PartialEq,

fn eq(&self, other: &ChargeAssetTxPayment<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: Config> TransactionExtension<<T as Config>::RuntimeCall> for ChargeAssetTxPayment<T>

where T::RuntimeCall: Dispatchable<Info = DispatchInfo, PostInfo = PostDispatchInfo>, <<T as Config>::OnChargeTransaction as OnChargeTransaction<T>>::Balance: Send + Sync + From<u64>, T::AssetId: Send + Sync, <T::RuntimeCall as Dispatchable>::RuntimeOrigin: AsSystemOriginSigner<T::AccountId> + Clone,

const IDENTIFIER: &'static str = "ChargeAssetTxPayment"

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<T>

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

type Pre = Pre<T>

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

fn weight(&self, _: &T::RuntimeCall) -> Weight

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

fn validate( &self, origin: <T::RuntimeCall as Dispatchable>::RuntimeOrigin, call: &T::RuntimeCall, info: &DispatchInfoOf<T::RuntimeCall>, len: usize, _self_implicit: Self::Implicit, _inherited_implication: &impl Encode, _source: TransactionSource, ) -> ValidateResult<Self::Val, T::RuntimeCall>

Validate a transaction for the transaction queue.

fn prepare( self, val: Self::Val, _origin: &<T::RuntimeCall as Dispatchable>::RuntimeOrigin, call: &T::RuntimeCall, info: &DispatchInfoOf<T::RuntimeCall>, _len: usize, ) -> Result<Self::Pre, TransactionValidityError>

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

fn post_dispatch_details( pre: Self::Pre, info: &DispatchInfoOf<T::RuntimeCall>, post_info: &PostDispatchInfoOf<T::RuntimeCall>, len: usize, _result: &DispatchResult, ) -> 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.

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
