Traits

• AnimatedValue
• AnyStorage

• AreaModel
• ComponentFunction

• Dependency
  A dependency is a trait that can be used to determine if a effect or selector should be re-run.
• HasAttributes

• IntoDynNode

• Properties
  Every “Props” used for a component must implement the Properties trait. This trait gives some hints to Dioxus on how to memoize the props and some additional optimizations that can be made. We strongly encourage using the derive macro to implement the Properties trait automatically as guarantee that your memoization strategy is safe.
• Readable
  A trait for states that can be read from like crate::Signal, crate::GlobalSignal, or crate::ReadOnlySignal. You may choose to accept this trait as a parameter instead of the concrete type to allow for more flexibility in your API. For example, instead of creating two functions, one that accepts a crate::Signal and one that accepts a crate::GlobalSignal, you can create one function that accepts a Readable type.
