Struct CompositeSignature 

pub struct CompositeSignature { /* private fields */ }

A composite signature — multiple algorithm components over the same message. Construct via CompositeSignature::from_json (the canonical wire format) and verify with CompositeSignature::verify.

Implementations

impl CompositeSignature

pub fn from_json(json: &str) -> Result<CompositeSignature, JsValue>

Parse a composite signature from its canonical JSON wire format.

{ "components": [
  { "algorithm": "Ed25519",
    "public_key": "<base64>",
    "signature": "<base64>" },
  ...
] }

pub fn component_count(&self) -> usize

Number of components.

pub fn algorithms(&self) -> Vec<String>

Algorithm identifiers in component order.

pub fn verify( &self, message: &[u8], ) -> Result<CompositeVerificationResult, JsValue>

Verify all components against message. Returns a CompositeVerificationResult describing per-component outcomes.

Built-in verifiers: Ed25519 + ECDSA-P256. Unknown algorithms are reported as failed components. JS callers needing ML-DSA-65 or SLH-DSA verification must preprocess the composite and supply their own verifier callback (Phase 2D).

Trait Implementations

impl From<CompositeSignature> for JsValue

fn from(value: CompositeSignature) -> Self

Converts to this type from the input type.

impl FromWasmAbi for CompositeSignature

type Abi = WasmPtr<WasmRefCell<CompositeSignature>>

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 CompositeSignature

type Abi = WasmPtr<WasmRefCell<CompositeSignature>>

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 CompositeSignature

type Abi = WasmPtr<WasmRefCell<CompositeSignature>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<CompositeSignature>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for CompositeSignature

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 CompositeSignature

fn none() -> Self::Abi

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

impl RefFromWasmAbi for CompositeSignature

type Abi = WasmPtr<WasmRefCell<CompositeSignature>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<CompositeSignature>

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 CompositeSignature

type Abi = WasmPtr<WasmRefCell<CompositeSignature>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<CompositeSignature>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl SupportsConstructor for CompositeSignature

impl SupportsInstanceProperty for CompositeSignature

impl SupportsStaticProperty for CompositeSignature

impl TryFromJsValue for CompositeSignature

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 CompositeSignature

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

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

impl VectorIntoWasmAbi for CompositeSignature

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

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

impl WasmDescribe for CompositeSignature

fn describe()

impl WasmDescribeVector for CompositeSignature

fn describe_vector()
