Expand description

Handles the functionality needed for persisting a non-parameter fields in a plugin’s state. These types can be used with Params’ #[persist = "..."] attributes.

This should be implemented for some type with interior mutability containing a T.

Required Methods§

fn set(&self, new_value: T)

Update the stored T value using interior mutability.

fn map<F, R>(&self, f: F) -> Rwhere F: Fn(&T) -> R,

Get a reference to the stored T value, and apply a function to it. This is used to serialize the T value.
