Struct MerkleRoot

pub struct MerkleRoot<H: Hasher>(/* private fields */);

A MerkleRoot contains the root hash of a MerkleTree.

Implementations

impl<H: Hasher> MerkleRoot<H>

Implements functionality for using standalone MerkleRoots.

pub fn new(root: H::Hash) -> Self

Construct a MerkleRoot from an existing Hash.

pub fn check(&self, proof: MerklePath<H>, item: &[u8]) -> bool

Given a item and corresponding MerklePath, check that it is a valid membership proof.

pub fn as_bytes(&self) -> &[u8]

Trait Implementations

impl<H: Hasher> BorshDeserialize for MerkleRoot<H>

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl<H: Hasher> BorshSerialize for MerkleRoot<H>

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl<H: Clone + Hasher> Clone for MerkleRoot<H>

where H::Hash: Clone,

fn clone(&self) -> MerkleRoot<H>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H: Debug + Hasher> Debug for MerkleRoot<H>

where H::Hash: Debug,

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

Formats the value using the given formatter.

impl<H: Default + Hasher> Default for MerkleRoot<H>

where H::Hash: Default,

fn default() -> MerkleRoot<H>

Returns the “default value” for a type.

impl<'de, H: Hasher> Deserialize<'de> for MerkleRoot<H>

where H::Hash: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<H: Hash + Hasher> Hash for MerkleRoot<H>

where H::Hash: Hash,

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<H: PartialEq + Hasher> PartialEq for MerkleRoot<H>

where H::Hash: PartialEq,

fn eq(&self, other: &MerkleRoot<H>) -> 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<H: Hasher> Serialize for MerkleRoot<H>

where H::Hash: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<H: Eq + Hasher> Eq for MerkleRoot<H>

where H::Hash: Eq,
