Struct ArbiterDB 

pub struct ArbiterDB {
    pub state: Arc<RwLock<CacheDB<EmptyDB>>>,
    pub logs: Arc<RwLock<HashMap<U256, Vec<Log>>>>,
}

A ArbiterDB is contains both a CacheDB that is used to provide state for the environment::Environment’s as well as for multiple coprocessor::Coprocessors. The logs field is a HashMap to store ethers::types::Logs that can be queried from at any point.

Fields

state: Arc<RwLock<CacheDB<EmptyDB>>>

The state of the ArbiterDB. This is a CacheDB that is used to provide a db for the Environment to use.

logs: Arc<RwLock<HashMap<U256, Vec<Log>>>>

The logs of the ArbiterDB. This is a HashMap that is used to store logs that can be queried from at any point.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Inspector<ArbiterDB> for ArbiterInspector

fn initialize_interp( &mut self, interp: &mut Interpreter, context: &mut EvmContext<ArbiterDB>, )

Called before the interpreter is initialized.

where __S: Serializer,

Serialize this value into the given Serde serializer.
