pub struct MyEvm<CTX, INSP>(pub Evm<CTX, INSP, EthInstructions<EthInterpreter, CTX>, EthPrecompiles, EthFrame<EthInterpreter>>);Expand description
MyEvm variant of the EVM.
This struct demonstrates how to create a custom EVM implementation by wrapping the standard REVM components. It combines a context (CTX), an inspector (INSP), and the standard Ethereum instructions, precompiles, and frame execution logic.
The generic parameters allow for flexibility in the underlying database and inspection capabilities while maintaining the standard Ethereum execution semantics.
