pub struct ModelWithPosition<M> { /* private fields */ }

ModelWithPosition is a helper to add the position to any model

Implementations

impl<M> ModelWithPosition<M>

where M: Dto,

pub const fn state(&self) -> &M

get the current state

pub fn play_event(&mut self, event: &M::Event, position: Option<u64>)

play one event to the current model to compute the next

pub const fn position(&self) -> Option<u64>

the position is the number of event in the event store None indicate that the topic is empty
