Struct evm_adapters::sputnik::cheatcodes::backend::CheatcodeBackend

pub struct CheatcodeBackend<B> {
    pub backend: B,
    pub cheats: Cheatcodes,
}

A cheatcode backend is a wrapper around the inner backend which returns the cheatcode value if it’s already been set, else it falls back to the default value inside the backend.

The cheatcode backend can be composed with other enhanced backends, e.g. the forking backend. You should always put the cheatcode backend on the highest layer of your stack of backend middlewares, so that it is always hit first.

Fields

backend: B

The inner backend type.

cheats: Cheatcodes

The enabled cheatcodes
