Trait TransactionSource 

pub trait TransactionSource {
    // Required method
    fn fetch_block_transactions(
        &self,
        block_number: u64,
    ) -> impl Future<Output = Result<Option<(Vec<RawTransaction>, u64)>>> + Send;
}

Abstraction over sources of transactions for big block generation.

Implementors provide transactions from different sources (RPC, database, files, etc.)

Required Methods

fn fetch_block_transactions( &self, block_number: u64, ) -> impl Future<Output = Result<Option<(Vec<RawTransaction>, u64)>>> + Send

Fetch transactions from a specific block number.

Returns Ok(None) if the block doesn’t exist. Returns Ok(Some((transactions, gas_used))) with the block’s transactions and total gas.

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.
