}Expand description
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.
If your props are ’static, then Dioxus will require that they also be PartialEq for the derived memoize strategy.
By default, the memoization strategy is very conservative, but can be tuned to be more aggressive manually. However, this is only safe if the props are ’static - otherwise you might borrow references after-free.
We strongly suggest that any changes to memoization be done at the “PartialEq” level for ’static props. Additionally, we advise the use of smart pointers in cases where memoization is important.
Example
For props that are ’static:
#[derive(Props, PartialEq, Clone)]
struct MyProps {
data: String
