Struct risc0_steel::host::db::ProviderDb

pub struct ProviderDb<N: Network, P: Provider<N>> { /* private fields */ }

Available on crate feature host only.

A [RevmDatabase] backed by an alloy [Provider].

When accessing the database, it’ll use the given provider to fetch the corresponding account’s data. It will block the current thread to execute provider calls, Therefore, its methods must not be executed inside an async runtime, or it will panic when trying to block. If the immediate context is only synchronous, but a transitive caller is async, use [tokio::task::spawn_blocking] around the calls that need to be blocked.
