Expand description

Extension trait for querying Ethereum-relevant state from a Filecoin actor.

Required Methods§

Source

fn eth_nonce<DB: Blockstore>(&self, store: &DB) -> Result<EthUint64>

Returns the effective nonce: EVM nonce for EVM actors (zero once self-destructed), sequence otherwise.

Source

fn eth_bytecode<DB: Blockstore>(&self, store: &DB) -> Result<Option<EthBytes>>

Returns the deployed bytecode of an EVM actor, or None for non-EVM or self-destructed actors.

Source

fn eth_storage_at<DB: Blockstore>( &self, store: &DB, position: &[u8; 32], ) -> Result<[u8; 32]>

Returns the 32-byte storage value at position, matching the EVM actor’s GetStorageAt: a zeroed word for a non-EVM actor, a dead (tombstoned) contract, or an unset slot.

Dyn Compatibility§

This trait is not dyn compatible.

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