Available on crate feature provider only.

Provides the state necessary for EVM execution.

Required Methods

fn basic_account( &self, address: &Address, ) -> Result<Option<Account>, ProviderError>

Returns the account, or None if it does not exist.

fn block_hash( &self, number: u64, ) -> Result<Option<FixedBytes<32>>, ProviderError>

Returns the block hash, or None if the block does not exist.

fn bytecode_by_hash( &self, code_hash: &FixedBytes<32>, ) -> Result<Option<Bytecode>, ProviderError>

Returns bytecode by its hash.

fn storage( &self, account: Address, storage_key: FixedBytes<32>, ) -> Result<Option<Uint<256, 4>>, ProviderError>

Returns the storage value of the given account and slot.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
