Struct ForkedDatabase

pub struct ForkedDatabase {

Expand description

a [revm::Database] that’s forked off another client

The backend is used to retrieve (missing) data, which is then fetched from the remote endpoint. The inner in-memory database holds this storage and will be used for write operations. This database uses the backend for read and the db for write operations. But note the backend will also write (missing) data to the db in the background
