Struct StorageChangeSets 

pub struct StorageChangeSets { /* private fields */ }
Expand description

Stores the state of a storage key before a certain transaction changed it. If [StorageEntry::value] is zero, this means storage was not existing and needs to be removed.

Marker type representing a database table mapping BlockNumberAddress to StorageEntry.

This table’s DUPSORT subkey is [B256].

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
