Struct StorageProof

pub struct StorageProof {
    pub key: FixedBytes<32>,
    pub nibbles: Nibbles,
    pub value: Uint<256, 4>,
    pub proof: Vec<Bytes>,
}

The merkle proof of the storage entry.

Fields

key: FixedBytes<32>

The raw storage key.

nibbles: Nibbles

The hashed storage key nibbles.

value: Uint<256, 4>

The storage value.

proof: Vec<Bytes>

Array of rlp-serialized merkle trie nodes which starting from the storage root node and following the path of the hashed storage slot as key.

Implementations

impl StorageProof

pub fn new(key: FixedBytes<32>) -> StorageProof

Create new storage proof from the storage slot.

pub fn new_with_hashed( key: FixedBytes<32>, hashed_key: FixedBytes<32>, ) -> StorageProof

Create new storage proof from the storage slot and its pre-hashed image.

pub fn new_with_nibbles(key: FixedBytes<32>, nibbles: Nibbles) -> StorageProof

Create new storage proof from the storage slot and its pre-hashed image.

pub fn with_proof(self, proof: Vec<Bytes>) -> StorageProof

Set proof nodes on storage proof.

pub fn verify(&self, root: FixedBytes<32>) -> Result<(), ProofVerificationError>

Verify the proof against the provided storage root.

Trait Implementations

impl Clone for StorageProof

fn clone(&self) -> StorageProof

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StorageProof

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for StorageProof

fn default() -> StorageProof

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageProof

fn deserialize<__D>( __deserializer: __D, ) -> Result<StorageProof, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StorageProof

fn eq(&self, other: &StorageProof) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for StorageProof

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for StorageProof

impl StructuralPartialEq for StorageProof

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.
