Expand description

Maybe this should rather be called “LazyUpdating”? Implementors can react to polling by queueing an update if needed. Update should force an update.

Required Methods§

source

fn poll_state(&mut self) -> &DataState

Polls the promise, triggers update if state is DataState::Uninitialized

source

fn update(&mut self)

Clears the data cache and immediately triggers an update
