This crate is part of the [`zng`](https://github.com/zng-ui/zng?tab=readme-ov-file#crates) project.
This crate provides 2 feature flags, 1 enabled by default.
Enables creation of separate or pre-build view.
When this is enabled communication with the view is (de)serialized which can add a
minor cost, something like a 1ms per 3MB frame request.
*Enabled by default.*
Implement `IntoVar<T>` for API types.
