Struct WasmStreamingDecoder

Implementations§

Source§

impl WasmStreamingDecoder

Source

pub fn new() -> Self

new streaming decoder

Source

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

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

Source

pub fn is_ready(&self) -> bool

Check if the decoder is ready to produce audio

Source

pub fn is_finished(&self) -> bool

stream done?

Source

pub fn has_error(&self) -> bool

Check if there was an error

Source

pub fn state(&self) -> String

Get the current state as a string

Source

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.

Source

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

decode all currently available samples

Source

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);
}
Source

pub fn available_frames(&self) -> usize

how many frames ready to decode

Source

pub fn current_frame_index(&self) -> usize

current frame index

Source

pub fn reset(&mut self)

Reset the decoder to initial state

Use this to start decoding a new stream.

Source

pub fn buffered_bytes(&self) -> usize

bytes currently buffered

impl OptionFromWasmAbi for WasmStreamingDecoder

Source§

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