Trait DatabaseAsyncRef

pub trait DatabaseAsyncRef {

    // Required methods
    fn basic_async_ref(

}

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

The database error type.

Required Methods

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

Get basic account information.

fn code_by_hash_async_ref( &self, code_hash: B256, ) -> impl Future<Output = Result<Bytecode, Self::Error>> + Send

Get account code by its hash.

fn storage_async_ref( &self, address: Address, index: U256, ) -> impl Future<Output = Result<U256, Self::Error>> + Send

Get storage value of address at index.

fn block_hash_async_ref( &self, number: u64, ) -> impl Future<Output = Result<B256, Self::Error>> + Send

Get 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.
