Trait StateReader

pub trait StateReader: Send + Sync {
    type Receipt: Send + Sync;

    // Required method
    fn get_state(
        &self,
        block: u64,
    ) -> Result<Option<ExecutionOutcome<Self::Receipt>>, ProviderError>;
}

This just receives state, or ExecutionOutcome, from the provider

Required Associated Types

type Receipt: Send + Sync

Receipt type in ExecutionOutcome.

Required Methods

fn get_state( &self, block: u64, ) -> Result<Option<ExecutionOutcome<Self::Receipt>>, ProviderError>

Get the ExecutionOutcome for the given block
