Trait EventEmitter 

pub trait EventEmitter:
    Send
    + Sync
    + 'static {
    // Required method
    fn emit(&self, event: &str, payload: Value);

    // Provided methods
    fn emit_json(&self, event: &str, payload: &RawValue) { ... }
    fn prefers_json(&self) -> bool { ... }
}

Emits events to the UI layer (Tauri frontend, CLI output, SDK callbacks).

Tauri: wraps AppHandle::emit(event, payload) CLI: logs to stdout or pushes to a channel SDK: invokes user-provided callbacks

Required Methods

fn emit(&self, event: &str, payload: Value)

Provided Methods

fn emit_json(&self, event: &str, payload: &RawValue)

Emit already-serialised JSON. The default parses it for EventEmitter::emit; emitters that forward JSON as-is override this and EventEmitter::prefers_json.

fn prefers_json(&self) -> bool

Whether EventEmitter::emit_json is cheaper than EventEmitter::emit here.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
