# Objective The default for `ContentSize` should have the `measure_func` field set to `None`, instead of a fixed size of zero. This means that until a measure func is set the size of the UI node will be determined by its `Style` constraints. This is preferable as it allows users to specify the space the Node should take up in the layout while waiting for content to load. ## Solution Derive `Default` for `ContentSize`. The PR also adds a `fixed_size` helper function to make it a bit easier to access the old behaviour. ## Changelog * Derived `Default` for `ContentSize` * Added a `fixed_size` helper function to `ContentSize` that creates a new `ContentSize` with a `MeasureFunc` that always returns the same value, regardless of layout constraints. ## Migration Guide The default for `ContentSize` now sets its `measure_func` to `None`, instead of a fixed size measure that returns `Vec2::ZERO`. The helper function `fixed_size` can be called with `ContentSize::fixed_size(Vec2::ZERO)` to get the previous behaviour. |
