Struct DecodedMessage 

pub struct DecodedMessage { /* private fields */ }

Handle to a decoded Tensogram message.

Owns the decoded payload data in WASM linear memory. Use the object_data_* methods to get zero-copy TypedArray views.

Important: The returned TypedArray views are invalidated if WASM memory grows. Read or copy the data before further WASM calls. Call .free() when done to release WASM memory.

Implementations

impl DecodedMessage

pub fn metadata(&self) -> Result<JsValue, JsValue>

Global metadata as a plain JS object. The wire-format version is synthesised from the preamble (v3: always 3) for TypeScript ergonomics — see metadata_to_js in convert.rs.

pub fn object_count(&self) -> usize

Number of data objects in the message.

pub fn object_descriptor(&self, index: usize) -> Result<JsValue, JsValue>

Object descriptor (shape, dtype, encoding, etc.) as a JS object.

pub fn object_data_f32(&self, index: usize) -> Result<Float32Array, JsValue>

Zero-copy Float32Array view into the decoded payload.

Warning: This view points directly into WASM linear memory. It becomes invalid if WASM memory grows. Read the data or pass it to WebGL before any further WASM calls.

pub fn object_data_f64(&self, index: usize) -> Result<Float64Array, JsValue>

Zero-copy Float64Array view.

pub fn object_data_i32(&self, index: usize) -> Result<Int32Array, JsValue>

Zero-copy Int32Array view.

pub fn object_data_u8(&self, index: usize) -> Result<Uint8Array, JsValue>

Zero-copy Uint8Array view.

pub fn object_data_copy_f32( &self, index: usize, ) -> Result<Float32Array, JsValue>

Safe-copy Float32Array (JS-heap owned, survives WASM memory growth).

pub fn object_byte_length(&self, index: usize) -> Result<usize, JsValue>

Raw payload byte length for object at index.

Trait Implementations

impl From<DecodedMessage> for JsValue

fn from(value: DecodedMessage) -> Self

Converts to this type from the input type.

impl FromWasmAbi for DecodedMessage

type Abi = u32

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

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for DecodedMessage

type Abi = u32

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

fn into_abi(self) -> u32

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

impl LongRefFromWasmAbi for DecodedMessage

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<DecodedMessage>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for DecodedMessage

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 DecodedMessage

fn none() -> Self::Abi

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

impl RefFromWasmAbi for DecodedMessage

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<DecodedMessage>

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 DecodedMessage

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<DecodedMessage>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for DecodedMessage

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 DecodedMessage

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

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

impl VectorIntoWasmAbi for DecodedMessage

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

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

impl WasmDescribe for DecodedMessage

fn describe()

impl WasmDescribeVector for DecodedMessage

fn describe_vector()

impl SupportsConstructor for DecodedMessage

impl SupportsInstanceProperty for DecodedMessage
