Available on crate features trie and trie-db only.

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

Required Associated Types

type Tx

Associated type for the database transaction.

Required Methods

fn from_tx(tx: &'a Self::Tx) -> Self

Create a new Proof instance from database transaction.

fn overlay_account_proof( &self, input: TrieInput, address: Address, slots: &[FixedBytes<32>], ) -> Result<AccountProof, StateProofError>

Generates the state proof for target account based on TrieInput.

fn overlay_multiproof( &self, input: TrieInput, targets: MultiProofTargets, ) -> Result<MultiProof, StateProofError>

Generates the state MultiProof for target hashed account and storage keys.

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.
