std::window::macos

std::window::macos is the macOS-specific facade for applications that want to select the macOS provider explicitly while still using the portable std::window types.

Exported API#

module std::window::macos;

import std::window;

export fn is_supported () -> bool;
export fn open (options: std::window::Options) -> std::window::WindowResult;

Semantics#

• is_supported() returns true only when the runtime selected std::window::Backend::MacOS.
• open(...) delegates to std::window::open(...) after checking that the macOS provider is active.
• On non-macOS targets, open(...) returns Err(UnsupportedPlatform).

Current provider

• The module is linkable, opts reachable std::window executables into the AppKit framework, and open(...) creates a visible provider-owned NSWindow on macOS targets.
• The portable std::window::next_event(...) call pumps at most one AppKit event, updates AppKit windows, and reports CloseRequested when the provider-owned NSWindow is no longer visible.
• poll(...) remains available as a compatibility liveness/update helper, and close(...) closes the provider-owned NSWindow.
• std::window native controls route to AppKit for title, visibility, focus, size, position, minimize/maximize/restore, always-on-top, screen size, and background color.
• The portable std::window::run(...) entrypoint opens a visible AppKit window and runs the application event loop until the user closes the last window.
• The portable std::window::run_loop(...) entrypoint owns open/event/close lifecycle for frame-rendering examples and calls the application callback while the AppKit window remains open.
