Trait BlockBodyReader

pub trait BlockBodyReader<Provider> {
    type Block: Block;

    // Required method
    fn read_block_bodies(
        &self,
        provider: &Provider,
        inputs: Vec<(&<Self::Block as Block>::Header, Vec<<<Self::Block as Block>::Body as BlockBody>::Transaction>)>,
    ) -> Result<Vec<<Self::Block as Block>::Body>, ProviderError>;
}

Trait that implements how block bodies are read from the storage.

Note: Within the current abstraction, transactions persistence is handled separately, thus this trait is provided with transactions read beforehand and is expected to construct the block body from those transactions and additional data read from elsewhere.

Required Associated Types

type Block: Block

The block type.

Required Methods

fn read_block_bodies( &self, provider: &Provider, inputs: Vec<(&<Self::Block as Block>::Header, Vec<<<Self::Block as Block>::Body as BlockBody>::Transaction>)>, ) -> Result<Vec<<Self::Block as Block>::Body>, ProviderError>

Receives a list of block headers along with block transactions and returns the block bodies.
