Expand description

Contains logic for stateless validations that don’t result in any reusable metadata such as spendable input balances or remaining gas. Primarily involves validating that transaction fields are correctly formatted and signed.

Required Methods§

source

fn check_signatures( &self, parameters: &ConsensusParameters ) -> Result<(), CheckError>

Validates that all required signatures are set in the transaction and that they are valid.

source

fn check_without_signatures( &self, block_height: BlockHeight, parameters: &ConsensusParameters ) -> Result<(), CheckError>

Validates the transactions according to rules from the specification: https://github.com/FuelLabs/fuel-specs/blob/master/src/protocol/tx_format/transaction.md#transaction

Provided Methods§

source

fn check( &self, block_height: BlockHeight, parameters: &ConsensusParameters ) -> Result<(), CheckError>

Performs all stateless transaction validity checks. This includes the validity of fields according to rules in the specification and validity of signatures.
