Struct WasmHashContext 

pub struct WasmHashContext { /* private fields */ }

WASM-compatible Hash context wrapper

This wrapper provides JavaScript-compatible bindings for hash operations:

• Integrates with the new modular architecture
• Includes security validation
• Provides consistent error handling
• Supports all hash algorithms

Implementations

impl WasmHashContext

pub fn new() -> WasmHashContext

Create a new WASM Hash context with default provider

pub fn from_hash_context(inner: HashContext) -> WasmHashContext

Wrap a Rust HashContext that already has a hash-capable provider (for example from lib-q-hash::LibQHashProvider in the umbrella crate).

impl WasmHashContext

pub fn with_provider(provider: &WasmCryptoProvider) -> WasmHashContext

Create a new WASM Hash context with custom provider

pub fn hash( &mut self, algorithm: &str, data: &Uint8Array, ) -> Result<JsValue, JsValue>

Hash data using the specified algorithm

pub fn security_level(&self) -> u32

Get the security level of the context

pub fn is_algorithm_supported(&self, algorithm: &str) -> bool

Check if an algorithm is supported

pub fn supported_algorithms(&self) -> String

Get supported algorithms

Trait Implementations

impl Default for WasmHashContext

fn default() -> WasmHashContext

Returns the “default value” for a type.

impl From<WasmHashContext> for JsValue

fn from(value: WasmHashContext) -> JsValue

Converts to this type from the input type.

impl FromWasmAbi for WasmHashContext

type Abi = WasmPtr<WasmRefCell<WasmHashContext>>

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

unsafe fn from_abi(js: <WasmHashContext as FromWasmAbi>::Abi) -> WasmHashContext

Recover a Self from Self::Abi.

impl IntoWasmAbi for WasmHashContext

type Abi = WasmPtr<WasmRefCell<WasmHashContext>>

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

fn into_abi(self) -> <WasmHashContext as IntoWasmAbi>::Abi

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

impl LongRefFromWasmAbi for WasmHashContext

type Abi = WasmPtr<WasmRefCell<WasmHashContext>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmHashContext>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi( js: <WasmHashContext as LongRefFromWasmAbi>::Abi, ) -> <WasmHashContext as LongRefFromWasmAbi>::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmHashContext

fn is_none(abi: &<WasmHashContext as FromWasmAbi>::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 WasmHashContext

fn none() -> <WasmHashContext as IntoWasmAbi>::Abi

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

impl RefFromWasmAbi for WasmHashContext

type Abi = WasmPtr<WasmRefCell<WasmHashContext>>

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmHashContext>

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: <WasmHashContext as RefFromWasmAbi>::Abi, ) -> <WasmHashContext as RefFromWasmAbi>::Anchor

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

impl RefMutFromWasmAbi for WasmHashContext

type Abi = WasmPtr<WasmRefCell<WasmHashContext>>

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmHashContext>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi( js: <WasmHashContext as RefMutFromWasmAbi>::Abi, ) -> <WasmHashContext as RefMutFromWasmAbi>::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WasmHashContext

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

Performs the conversion.

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

Performs the conversion.

impl VectorFromWasmAbi for WasmHashContext

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

unsafe fn vector_from_abi( js: <WasmHashContext as VectorFromWasmAbi>::Abi, ) -> Box<[WasmHashContext]>

impl VectorIntoWasmAbi for WasmHashContext

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

fn vector_into_abi( vector: Box<[WasmHashContext]>, ) -> <WasmHashContext as VectorIntoWasmAbi>::Abi
