Struct MultiProof 

pub struct MultiProof {
    pub account_subtree: ProofNodes,
    pub branch_node_masks: HashMap<Nibbles, BranchNodeMasks, DefaultHashBuilder>,
    pub storages: HashMap<FixedBytes<32>, StorageMultiProof, FbBuildHasher<32>>,
}

The state multiproof of target accounts and multiproofs of their storage tries. Multiproof is effectively a state subtrie that only contains the nodes in the paths of target accounts.

Fields

account_subtree: ProofNodes

State trie multiproof for requested accounts.

branch_node_masks: HashMap<Nibbles, BranchNodeMasks, DefaultHashBuilder>

Consolidated branch node masks (hash_mask, tree_mask) for each path in the account proof.

storages: HashMap<FixedBytes<32>, StorageMultiProof, FbBuildHasher<32>>

Storage trie multiproofs.

Implementations

impl MultiProof

pub fn is_empty(&self) -> bool

Returns true if the multiproof is empty.

pub fn account_proof_nodes(&self, path: &Nibbles) -> Vec<(Nibbles, Bytes)>

Return the account proof nodes for the given account path.

pub fn storage_proof_nodes( &self, hashed_address: FixedBytes<32>, slots: impl IntoIterator<Item = FixedBytes<32>>, ) -> Vec<(FixedBytes<32>, Vec<(Nibbles, Bytes)>)>

Return the storage proof nodes for the given storage slots of the account path.

pub fn account_proof( &self, address: Address, slots: &[FixedBytes<32>], ) -> Result<AccountProof, Error>

Construct the account proof from the multiproof.

pub fn extend(&mut self, other: MultiProof)

Extends this multiproof with another one, merging both account and storage proofs.

pub fn from_storage_proof( hashed_address: FixedBytes<32>, storage_proof: StorageMultiProof, ) -> MultiProof

Create a MultiProof from a StorageMultiProof.

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.
