A trait for validating transactions

Required Methods

fn validate_pool_transaction<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 PendingTransaction, ) -> Pin<Box<dyn Future<Output = Result<(), BlockchainError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Validates the transaction’s validity when it comes to nonce, payment

This is intended to be checked before the transaction makes it into the pool and whether it should rather be outright rejected if the sender has insufficient funds.

fn validate_pool_transaction_for( &self, tx: &PendingTransaction, account: &AccountInfo, env: &EnvWithHandlerCfg, ) -> Result<(), InvalidTransactionError>

Validates the transaction against a specific account before entering the pool

fn validate_for( &self, tx: &PendingTransaction, account: &AccountInfo, env: &EnvWithHandlerCfg, ) -> Result<(), InvalidTransactionError>

Validates the transaction against a specific account

This should succeed if the transaction is ready to be executed
