Struct WasmStreamingDecoder 

pub struct WasmStreamingDecoder { /* private fields */ }

Implementations

impl WasmStreamingDecoder

pub fn new() -> Self

new streaming decoder

pub fn feed(&mut self, data: &[u8]) -> Result<bool, JsValue>

feed data to the decoder, call as bytes come in from network

pub fn is_ready(&self) -> bool

Check if the decoder is ready to produce audio

pub fn is_finished(&self) -> bool

stream done?

pub fn has_error(&self) -> bool

Check if there was an error

pub fn state(&self) -> String

Get the current state as a string

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

Get audio information (available after header is parsed)

Returns null if header hasn’t been parsed yet.

pub fn decode_available(&mut self) -> Result<Vec<f32>, JsValue>

decode all currently available samples

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

Decode the next available frame

Returns interleaved f32 samples for one frame, or null if no frame is ready. This enables true streaming: decode and play frames as they arrive.

Usage pattern:

while (true) {
    const samples = decoder.next_frame();
    if (samples === null) break; // No more frames ready
    playAudio(samples);
}

pub fn available_frames(&self) -> usize

how many frames ready to decode

pub fn current_frame_index(&self) -> usize

current frame index

pub fn reset(&mut self)

Reset the decoder to initial state

Use this to start decoding a new stream.

pub fn buffered_bytes(&self) -> usize

bytes currently buffered

Trait Implementations

impl Default for WasmStreamingDecoder

fn default() -> Self

Returns the “default value” for a type.

impl From<WasmStreamingDecoder> for JsValue

fn from(value: WasmStreamingDecoder) -> Self

Converts to this type from the input type.

impl FromWasmAbi for WasmStreamingDecoder

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 WasmStreamingDecoder

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 WasmStreamingDecoder

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<WasmStreamingDecoder>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for WasmStreamingDecoder

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 WasmStreamingDecoder

fn none() -> Self::Abi

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

impl RefFromWasmAbi for WasmStreamingDecoder

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<WasmStreamingDecoder>

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 WasmStreamingDecoder

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<WasmStreamingDecoder>

Same as RefFromWasmAbi::Anchor

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

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for WasmStreamingDecoder

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 WasmStreamingDecoder

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

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

impl VectorIntoWasmAbi for WasmStreamingDecoder

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

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