Struct reth_provider::providers::BlockchainProvider2

pub struct BlockchainProvider2<N: NodeTypesWithDB> { /* private fields */ }

The main type for interacting with the blockchain.

This type serves as the main entry point for interacting with the blockchain and provides data from database storage and from the blockchain tree (pending state etc.) It is a simple wrapper type that holds an instance of the database and the blockchain tree.

Implementations

impl<N: ProviderNodeTypes> BlockchainProvider2<N>

pub fn new(database: ProviderFactory<N>) -> ProviderResult<Self>

Create a new provider using only the database, fetching the latest header from the database to initialize the provider.
