Trait Update 

pub trait Update<S> {
    type Interest: FieldInterests;

    // Required method
    fn update(
        &mut self,
        event: EventWithInterest<Self::Interest>,
    ) -> Result<UpdateResult<'_, S, Self::Interest>, UpdateError>;
}

A trait for types holding interface state that can be updated by change events.

Required Associated Types

type Interest: FieldInterests

The expected watcher interest type for this update target.

Required Methods

fn update( &mut self, event: EventWithInterest<Self::Interest>, ) -> Result<UpdateResult<'_, S, Self::Interest>, UpdateError>

Update state with the interface change event.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
