Struct ObservedContext 

pub struct ObservedContext<'a, 'o, C: ContextAccess> { /* private fields */ }

A ContextAccess wrapper that delegates to an inner ContextAccess implementor (typically World or the ContextView routing view) and notifies a WriteObserver on every mutation.

Generic over the wrapped implementor so it composes with the routing view: ObservedContext::new(&mut ContextView::new(&mut world, &mut local), observer) observes exactly what the VM sees, regardless of how many layers the routing view has behind it.

Implementations

impl<'a, 'o, C: ContextAccess> ObservedContext<'a, 'o, C>

pub fn new(context: &'a mut C, observer: &'o mut dyn WriteObserver) -> Self

Trait Implementations

impl<C: ContextAccess> ContextAccess for ObservedContext<'_, '_, C>

fn global(&self, idx: u32) -> &Value

fn set_global(&mut self, idx: u32, value: Value)

fn visit_count(&self, id: DefinitionId) -> u32

fn increment_visit(&mut self, id: DefinitionId)

fn set_visit_count(&mut self, id: DefinitionId, count: u32)

Set a visit count directly, rather than incrementing it. Used by crate::load_state to reconcile a durable save, whose entries carry absolute counts rather than deltas.

fn turn_count(&self, id: DefinitionId) -> Option<u32>

fn set_turn_count(&mut self, id: DefinitionId, turn: u32)

fn turn_index(&self) -> u32

fn increment_turn_index(&mut self)

fn set_turn_index(&mut self, index: u32)

Set the turn index directly, rather than incrementing it. Used by crate::load_state to restore a saved turn index.

fn rng_seed(&self) -> i32

fn set_rng_seed(&mut self, seed: i32)

fn previous_random(&self) -> i32

fn set_previous_random(&mut self, val: i32)

fn next_random<R: StoryRng>(&self, seed: i32) -> i32

fn random_sequence<R: StoryRng>(&self, seed: i32, count: usize) -> Vec<i32>
