Struct OverriddenSimulationDB 

pub struct OverriddenSimulationDB<'a, DB: DatabaseRef> {
    pub inner_db: &'a DB,
    pub overrides: &'a HashMap<Address, HashMap<U256, U256>>,
    pub native_balance_overrides: &'a HashMap<Address, U256>,
}

A wrapper over an actual SimulationDB that allows overriding specific storage slots and native balances

Fields

inner_db: &'a DB

Wrapped database. Will be queried if a requested item is not found in the overrides.

overrides: &'a HashMap<Address, HashMap<U256, U256>>

A mapping from account address to storage. Storage is a mapping from slot index to slot value.

native_balance_overrides: &'a HashMap<Address, U256>

A mapping from account address to its overridden native balance. An override for an account absent from the inner database materializes it as an empty account holding that balance.

Implementations

impl<'a, DB: DatabaseRef> OverriddenSimulationDB<'a, DB>

pub fn new( inner_db: &'a DB, overrides: &'a HashMap<Address, HashMap<U256, U256>>, native_balance_overrides: &'a HashMap<Address, U256>, ) -> Self

Creates a new OverriddenSimulationDB.
