zng::view_process::default

Function run_same_process

source
pub fn run_same_process(run_app: impl FnOnce() + Send + 'static)
Expand description

Runs the view-process server in the current process and calls run_app to also run the app in the current process. Note that run_app will be called in a different thread.

In this mode the app only uses a single process, reducing the memory footprint, but it is also not resilient to video driver crashes, the view server does not respawn in this mode.

§Panics

Panics if not called in the main thread, this is a requirement of some operating systems.

§Background Panics Warning

Note that webrender can freeze due to panics in worker threads without propagating the panics to the main thread, this causes the app to stop responding while still receiving event signals, causing the operating system to not detect that the app is frozen. It is recommended that you build with panic=abort or use std::panic::set_hook to detect these background panics.

§Android

In Android builds android::init_android_app must be called before this function, otherwise it will panic.
