Required Methods

fn build_spec(genesis: &Genesis) -> Result<Arc<Self::ChainSpec>, ClientError>

fn validate_header( header: &SealedHeader, chain_spec: Arc<Self::ChainSpec>, ) -> Result<(), ConsensusError>

fn transact<DB>( input: &ContractInput, db: DB, header: &Header, difficulty: U256, chain_spec: Arc<Self::ChainSpec>, ) -> Result<ResultAndState<Self::HaltReason>, String>

where DB: Database,

fn active_fork_name(chain_spec: &Self::ChainSpec, header: &Header) -> String

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
