Module ipc 

IPC message contracts for WebView ↔ Rust communication

This module defines JSON-RPC 2.0 style messages used for bidirectional communication between the React UI (running in WebView) and the Rust application logic.

Architecture

• Request/Response: UI initiates, Rust responds (e.g., setParameter, getParameter)
• Notifications: Rust pushes updates to UI (e.g., parameter changes from host)

JSON-RPC 2.0 Compatibility

Messages follow JSON-RPC 2.0 conventions:

• Requests have id, method, and params
• Responses have id and either result or error
• Notifications have method and params but no id

Structs

GetAllParametersResult

Result of getAllParameters request

GetMeterFrameResult

Result for getMeterFrame method

GetParameterParams

Parameters for getParameter request

GetParameterResult

Result of getParameter request

IpcError

Error returned in IpcResponse

IpcNotification

Notification message sent from Rust to UI (no response expected)

IpcRequest

Request message sent from UI to Rust

IpcResponse

Response message sent from Rust to UI

MeterFrame

Meter frame data for UI visualization.

MeterUpdateNotification

Notification sent from audio binary to browser via dev server

ParameterChangedNotification

Notification sent when a parameter changes (e.g., from host automation)

ParameterInfo

Information about a single parameter

RegisterAudioParams

Parameters for registerAudio request (audio binary → dev server)

RegisterAudioResult

Result of registerAudio request

RequestResizeParams

Parameters for requestResize request

RequestResizeResult
