Trait DatabaseStorageRoot 

pub trait DatabaseStorageRoot<'a, TX> {
    // Required methods
    fn from_tx(tx: &'a TX, address: Address) -> Self;
    fn from_tx_hashed(tx: &'a TX, hashed_address: FixedBytes<32>) -> Self;
    fn overlay_root(
        tx: &'a TX,
        address: Address,
        hashed_storage: HashedStorage,
    ) -> Result<FixedBytes<32>, StorageRootError>;
}

Available on crate features trie and trie-db only.

Extends StorageRoot with operations specific for working with a database transaction.

Required Methods

fn from_tx(tx: &'a TX, address: Address) -> Self

Create a new storage root calculator from database transaction and raw address.

fn from_tx_hashed(tx: &'a TX, hashed_address: FixedBytes<32>) -> Self

Create a new storage root calculator from database transaction and hashed address.

fn overlay_root( tx: &'a TX, address: Address, hashed_storage: HashedStorage, ) -> Result<FixedBytes<32>, StorageRootError>

Calculates the storage root for this HashedStorage and returns it.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
