Struct MerkleTree 

pub struct MerkleTree { /* private fields */ }

Append-only Merkle tree mirroring confium_transparency::MerkleTree.

Browser-side consumers typically receive a tree head (root hash + size) from a server and verify inclusion proofs against it. This class also supports building trees locally for testing.

Implementations

impl MerkleTree

pub fn new() -> MerkleTree

Construct an empty tree.

pub fn append(&self, artifact_hash: &[u8]) -> Result<u64, JsValue>

Append a 32-byte artifact hash. Returns the assigned sequence number.

pub fn length(&self) -> usize

Current number of leaves.

pub fn root(&self) -> Vec<u8>

Current 32-byte root.

pub fn consistency_proof(&self, old_size: usize) -> Result<Vec<u8>, JsValue>

Build a consistency proof (RFC 6962 §2.1.2) for old_size. Returns a flat array of 32-byte subtree hashes concatenated (total length = proof.len() * 32).

pub fn inclusion_proof(&self, sequence: u64) -> Result<InclusionProof, JsValue>

Build an inclusion proof for sequence.

Trait Implementations

impl Default for MerkleTree

fn default() -> Self

Returns the “default value” for a type.

impl From<MerkleTree> for JsValue

fn from(value: MerkleTree) -> Self

Converts to this type from the input type.

impl FromWasmAbi for MerkleTree

type Abi = WasmPtr<WasmRefCell<MerkleTree>>

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: Self::Abi) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for MerkleTree

type Abi = WasmPtr<WasmRefCell<MerkleTree>>

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> Self::Abi

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for MerkleTree

type Abi = WasmPtr<WasmRefCell<MerkleTree>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<MerkleTree>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for MerkleTree

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for MerkleTree

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for MerkleTree

type Abi = WasmPtr<WasmRefCell<MerkleTree>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<MerkleTree>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for MerkleTree

type Abi = WasmPtr<WasmRefCell<MerkleTree>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<MerkleTree>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for MerkleTree

impl SupportsInstanceProperty for MerkleTree

impl SupportsStaticProperty for MerkleTree

impl TryFromJsValue for MerkleTree

fn try_from_js_value(value: JsValue) -> Result<Self, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<Self>

Performs the conversion.

impl VectorFromWasmAbi for MerkleTree

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi(js: Self::Abi) -> Box<[MerkleTree]>

impl VectorIntoWasmAbi for MerkleTree

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi(vector: Box<[MerkleTree]>) -> Self::Abi

impl WasmDescribe for MerkleTree

fn describe()

impl WasmDescribeVector for MerkleTree

fn describe_vector()
