Module ringbuf 

In-process ring buffer for high-frequency streaming.

RingBuffer is the breakthrough component of tauri-conduit: an in-process circular buffer that lets the Rust backend stream binary frames to the WebView frontend without serialization, IPC, or inter-process shared memory. The custom protocol handler (conduit://) reads directly from it.

Design

The buffer stores variable-length frames with a configurable byte budget (default 64 KB). When the budget is exceeded, the oldest frames are dropped to make room — this is lossy by design, because the JS consumer is expected to drain fast enough for real-time use cases (market data, sensor telemetry, audio buffers).
