Used in Foundry to provide extended functionality to cheatcodes. The methods are called from the Cheatcodes inspector.

Required Methods

fn method_that_takes_inspector_as_argument<InspectorT, BlockT, TxT, CfgT, PrecompileT>( &mut self, env: Env<BlockT, TxT, CfgT>, inspector: InspectorT, ) -> Result<()>

where InspectorT: Inspector<Context<BlockT, TxT, CfgT, InMemoryDB, Backend>, EthInterpreter> + GetInspector<Context<BlockT, TxT, CfgT, InMemoryDB, Backend>, EthInterpreter>, BlockT: Block, TxT: Transaction, CfgT: Cfg, PrecompileT: PrecompileProvider<Context = InspectorContext<InspectorT, InMemoryDB, Context<BlockT, TxT, CfgT, InMemoryDB, Backend>>, Output = InterpreterResult, Error = EVMError<Infallible, InvalidTransaction>>,

Mimics DatabaseExt::transact See commit_transaction for the generics

fn method_that_constructs_inspector<BlockT, TxT, CfgT>( &mut self, env: Env<BlockT, TxT, CfgT>, ) -> Result<()>

where BlockT: Block, TxT: Transaction, CfgT: Cfg,

Mimics DatabaseExt::roll_fork_to_transaction

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.
