Window

Create a GLFW window for Vulkan, process events and obtain the extensions and surface required for presentation. Import window; its Vulkan dependency is loaded transitively. A display, GLFW and a usable Vulkan loader/driver are needed when graphics functions run.

First example

import window
let window_example = fn () -> i64 {
    if !Window:initialize() { return 1 }
    defer Window:shutdown()
    let window = Window:create_vulkan(800, 600, "RecurLoop", Window:True())
    if !window { return 2 }
    defer Window:destroy(window)
    while !Window:should_close(window) { Window:wait() }
    return 0
}
// Call window_example() in a graphical session.

This creates a window without a graphics context; it does not draw a Vulkan frame. Closing it exits the loop, destroys the window and then shuts GLFW down. initialize returns 0 when initialization or the Vulkan-support check fails.

Importing the vocabulary alone does not initialize GLFW or open windows.

Learning path

1. Event loop — Choose polling or waiting and handle close requests.
2. Input and time — Read cached input and measure elapsed time.
3. Vulkan surfaces — Create a surface with correct lifetime and pixel extent.
