Struct ServerValueChange 

pub struct ServerValueChange<'a> {
    pub equal: bool,
    pub old_resource: Option<Rc<dyn IServerRenderResource>>,
    pub new_resource: Option<Rc<dyn IServerRenderResource>>,
    pub assign: &'a mut dyn FnMut(),
}

One assignment of a property field, in the form SetValue(prop, ref field, value) takes it upstream: the class decides what else happens around the assignment.

Fields

equal: bool

Whether the new value equals the current one.

old_resource: Option<Rc<dyn IServerRenderResource>>

The render resource behind the current value, if it is one.

new_resource: Option<Rc<dyn IServerRenderResource>>

The render resource behind the new value, if it is one.

assign: &'a mut dyn FnMut()

Performs field = value.
