Struct AccountEntrypointMetaPaymentMethod 

pub struct AccountEntrypointMetaPaymentMethod { /* private fields */ }

Wraps a FeePaymentMethod so that fee payment is routed through the account contract’s entrypoint. This enables an account to pay for its own deployment transaction.

The inner payment method’s execution payload gets wrapped as a call to the account’s entrypoint() function with the appropriate fee payment method option.

Implementations

impl AccountEntrypointMetaPaymentMethod

pub fn new( account: Arc<dyn Account>, inner: Option<Arc<dyn FeePaymentMethod>>, fee_entrypoint_options: Option<DefaultAccountEntrypointOptions>, ) -> AccountEntrypointMetaPaymentMethod

Create a new meta payment method.

• account: The account whose entrypoint will handle fee payment.
• inner: Optional inner fee payment method. If None, assumes the account pays from its existing Fee Juice balance.
• fee_entrypoint_options: Optional explicit entrypoint options. If None, auto-detects based on fee payer and inner calls.

Trait Implementations

impl FeePaymentMethod for AccountEntrypointMetaPaymentMethod

fn get_asset<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<AztecAddress, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, AccountEntrypointMetaPaymentMethod: 'async_trait,

Returns the address of the asset used for fee payment. For fee juice methods, this is the FeeJuice protocol contract address.

fn get_fee_payer<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<AztecAddress, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, AccountEntrypointMetaPaymentMethod: 'async_trait,

Returns the address of the entity paying the fee.

fn get_fee_execution_payload<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<ExecutionPayload, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, AccountEntrypointMetaPaymentMethod: 'async_trait,

Builds an ExecutionPayload containing the function calls and auth witnesses needed to pay the transaction fee.
