Struct PrimaryHandle 

pub struct PrimaryHandle { /* private fields */ }

A handle representing the primary (first) instance of the application.

Holds the IPC listener alive for the lifetime of the application. When dropped, cleans up the socket file on Unix platforms.

This is non-blocking and is intended to be polled from the application’s main loop, for example to bring the existing window to the foreground.
