Struct solana_shadow::BlockchainShadow

pub struct BlockchainShadow { /* private fields */ }

The entry point to the Solana Blockchain Shadow API

This type allows its users to monitor several individual accounts or all accounts of a program, or a combination of both for any changes to those accounts and have the most recent version of those accounts available locally and accessible as if they were stored in a local hashmap<Pubkey, Account>
