[−][src]Struct elrond_wasm::storage::mut_storage::BorrowedMutStorage

pub struct BorrowedMutStorage<'a, A, BigInt, BigUint, T> where
    BigInt: Encode + 'static,
    BigUint: Encode + 'static,
    A: ContractHookApi<BigInt, BigUint> + ContractIOApi<BigInt, BigUint> + 'a,
    T: Encode + Decode,  { /* fields omitted */ }

Contains a value taken from storage and a reference to the api. The value can be changed and will be saved back to storage when the lifetime of the BorrowedMutStorage expires. Optimization: will only save back to storage if the value is referenced with deref_mut(), because only in such way can it be changed.
