Struct MerkleReceipt 

pub struct MerkleReceipt {
    pub start: Vec<u8>,
    pub start_index: i64,
    pub end: Vec<u8>,
    pub end_index: i64,
    pub anchor: Vec<u8>,
    pub entries: Vec<MerkleReceiptEntry>,
}

Merkle receipt - cryptographic proof of inclusion in a Merkle tree Used for anchoring transactions and proving state inclusion

Fields

start: Vec<u8>

The starting entry hash for which we want a proof

start_index: i64

Index of the start entry in the chain

end: Vec<u8>

The ending entry hash at the anchor point

end_index: i64

Index of the end entry in the chain

anchor: Vec<u8>

The Merkle root hash expected after applying all proof entries

entries: Vec<MerkleReceiptEntry>

The list of hashes in the proof path

Implementations

impl MerkleReceipt

pub fn new() -> Self

Create an empty receipt

pub fn validate(&self) -> Result<(), Error>

Validate the receipt structure

pub fn verify(&self) -> Result<bool, Error>

Verify the receipt by computing the Merkle proof Returns true if applying the entries produces the expected anchor

pub fn is_empty(&self) -> bool

Check if the receipt is empty

Trait Implementations

impl Clone for MerkleReceipt

fn clone(&self) -> MerkleReceipt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MerkleReceipt

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

Formats the value using the given formatter.

impl Default for MerkleReceipt

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MerkleReceipt

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for MerkleReceipt

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MerkleReceipt

fn eq(&self, other: &MerkleReceipt) -> 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 MerkleReceipt

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
