The async EVM database interface

Contains the same methods as DatabaseRef, but it returns Future type instead.

Use WrapDatabaseAsync to provide DatabaseRef implementation for a type that only implements this trait.

Required Associated Types

type Error: Send + DBErrorMarker + Error

The database error type

Required Methods

fn basic_async_ref( &self, address: Address, ) -> impl Future<Output = Result<Option<AccountInfo>, Self::Error>> + Send

Gets basic account information.

fn code_by_hash_async_ref( &self, code_hash: FixedBytes<32>, ) -> impl Future<Output = Result<Bytecode, Self::Error>> + Send

Gets account code by its hash.

fn storage_async_ref( &self, address: Address, index: Uint<256, 4>, ) -> impl Future<Output = Result<Uint<256, 4>, Self::Error>> + Send

Gets storage value of address at index.

fn block_hash_async_ref( &self, number: u64, ) -> impl Future<Output = Result<FixedBytes<32>, Self::Error>> + Send

Gets block hash by block number.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
