Available on crate feature storage-api only.

A type that can generate state proof on top of a given post state.

Required Methods

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

Get account and storage proofs of target keys in the HashedPostState on top of the current state.

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

Generate MultiProof for target hashed account and corresponding hashed storage slot keys.

fn witness( &self, input: TrieInput, target: HashedPostState, mode: ExecutionWitnessMode, ) -> Result<Vec<Bytes>, ProviderError>

Get trie witness for provided state using the given witness generation mode.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
