Module window 

The window’s measured size, and the hook components read it through.

The UI is authored here but measured by the Renderer, so the only way a Rust component can know how wide the window is, is for the Renderer to tell it. The Renderer sends one event when the size class changes and nothing in between, so this module is a single current value plus the list of components that asked to be told when it changes.

Structs

NodeSize

Reads the window’s size class inside a component, and re-renders it when the class changes.

WindowSize

The window’s size, as the Renderer last measured it.

Functions

node_size

The size a node last measured, or a zero size for one nothing has reported yet.

use_node_size

Follows one node’s size, and re-renders this component when its class changes.

use_window_size

window_size

The size the Renderer last reported. Available outside a component too.
