The async EVM database interface

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

Use WrapDatabaseAsync to provide Database 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( &mut self, address: Address, ) -> impl Future<Output = Result<Option<AccountInfo>, Self::Error>> + Send

Gets basic account information.

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

Gets account code by its hash.

fn storage_async( &mut 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( &mut 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.
