Module runtime 

Runtime

The Bubba runtime — bridges Rust UI logic to Android native views, exactly like React Native’s bridge between JS and UIManager.

Architecture

Rust view! macro  →  Element tree  →  JSON
                                        ↓
                                   JNI bridge
                                        ↓
                                 ViewInflater.java
                                        ↓
                           Real Android Views (TextView, Button…)
                                        ↓
                              User taps button
                                        ↓
                          nativeOnEvent(id, "click", "")
                                        ↓
                         Rust EventDispatcher fires handler
                                        ↓
                         navigate() → new Element tree → JSON
                                        ↓
                              Java re-inflates Views

Structs

Runtime

The Bubba runtime. One per process.

Constants

BUBBA_VERSION

Bubba runtime version.

Functions

alert

Show a native alert dialog.

did_navigate

Returns true if a navigation event occurred since the last render. Called by Java after every nativeOnEvent() to know if it should re-render.

dispatch_event

Dispatch an event from Java into the matching Rust EventHandler.

log_msg

Log a debug message.

on_navigate

Called internally when navigate() fires so Java knows to re-render.

render_current_to_json

Build the current screen’s element tree, register its handlers, and return the JSON string to send to Java’s ViewInflater.

set_global_runtime

Register the runtime for use by spawn().

spawn

Spawn a future on the async executor.
