Provides call and call_many methods

Associated Types

type State: StateInfo

Type representing chain state

Required Methods

fn call(
    &self,
    tx: &SignedTransaction,
    analytics: CallAnalytics,
    state: &mut Self::State,
    header: &Header
) -> Result<Executed, CallError>

Makes a non-persistent transaction call.

fn call_many(
    &self,
    txs: &[(SignedTransaction, CallAnalytics)],
    state: &mut Self::State,
    header: &Header
) -> Result<Vec<Executed>, CallError>

Makes multiple non-persistent but dependent transaction calls. Returns a vector of successes or a failure if any of the transaction fails.

fn estimate_gas(
    &self,
    t: &SignedTransaction,
    state: &Self::State,
    header: &Header
) -> Result<U256, CallError>

Estimates how much gas will be necessary for a call.
