Trait DatabaseHashedPostState 

pub trait DatabaseHashedPostState<TX>: Sized {
    // Required method
    fn from_reverts<KH: KeyHasher>(
        tx: &TX,
        range: impl RangeBounds<BlockNumber>,
    ) -> Result<HashedPostStateSorted, DatabaseError>;
}

Extends [HashedPostStateSorted] with operations specific for working with a database transaction.

Required Methods

fn from_reverts<KH: KeyHasher>( tx: &TX, range: impl RangeBounds<BlockNumber>, ) -> Result<HashedPostStateSorted, DatabaseError>

Initializes [HashedPostStateSorted] from reverts. Iterates over state reverts in the specified range and aggregates them into sorted hashed state.

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.

Implementations on Foreign Types

impl<TX: DbTx> DatabaseHashedPostState<TX> for HashedPostStateSorted

fn from_reverts<KH: KeyHasher>( tx: &TX, range: impl RangeBounds<BlockNumber>, ) -> Result<Self, DatabaseError>

Builds a sorted hashed post-state from reverts.

Reads MDBX data directly into Vecs, using HashSets only to track seen keys. This avoids intermediate HashMap allocations since MDBX data is already sorted.

• Reads the first occurrence of each changed account/storage slot in the range.
• Hashes keys and returns them already ordered for trie iteration.
