Struct ModelStore 

pub struct ModelStore { /* private fields */ }

Main-thread-only storage for typed models.

ModelStore is an Rc-backed container that holds model values behind type-erased entries and provides leasing-based read/update access.

Key properties:

• Models are removed when their last strong Model<T> handle is dropped.
• take_changed_models provides an incremental change list for driving UI updates.
• In debug/strict modes, the store tracks lease locations to surface misuse early.

Implementations

impl ModelStore

pub fn debug_created_info_for_id( &self, id: ModelId, ) -> Option<ModelCreatedDebugInfo>

pub fn debug_last_changed_info_for_id( &self, id: ModelId, ) -> Option<ModelChangedDebugInfo>

pub fn take_changed_models(&mut self) -> Vec<ModelId>

Returns and clears the list of models that were marked changed since the last call.

Dropped models are filtered out.

pub fn insert<T: Any>(&mut self, value: T) -> Model<T>

pub fn read<T: Any, R>( &self, model: &Model<T>, f: impl FnOnce(&T) -> R, ) -> Result<R, ModelUpdateError>

pub fn try_get_copied<T: Any + Copy>( &self, model: &Model<T>, ) -> Result<Option<T>, ModelUpdateError>

pub fn get_copied<T: Any + Copy>(&self, model: &Model<T>) -> Option<T>

pub fn try_get_cloned<T: Any + Clone>( &self, model: &Model<T>, ) -> Result<Option<T>, ModelUpdateError>

pub fn get_cloned<T: Any + Clone>(&self, model: &Model<T>) -> Option<T>

pub fn revision<T: Any>(&self, model: &Model<T>) -> Option<u64>

pub fn update<T: Any, R>( &mut self, model: &Model<T>, f: impl FnOnce(&mut T) -> R, ) -> Result<R, ModelUpdateError>

pub fn update_any<R>( &mut self, id: ModelId, f: impl FnOnce(&mut dyn Any) -> R, ) -> Result<R, ModelUpdateError>

pub fn notify_with_changed_at<T: Any>( &mut self, model: &Model<T>, changed_at: &'static Location<'static>, ) -> Result<(), ModelUpdateError>

pub fn notify<T: Any>( &mut self, model: &Model<T>, ) -> Result<(), ModelUpdateError>
