1//! Anchor-based window placement: the types describing a placement request.
2//!
3//! The `xdg_positioner`-style algorithm that resolves these into a concrete position and size
4//! lives in `winit-common`, since it's only needed by backends without a native equivalent of
5//! Wayland's `xdg_positioner` (such as Win32 and AppKit) and isn't part of winit's public API.
