Struct CacheView 

pub struct CacheView { /* private fields */ }

Read-only view over the platform cache.

Adapter-facing code receives this type instead of the mutable cache handle so cache writes stay owned by the data and execution engines.

Implementations

impl CacheView

pub fn new(inner: Rc<RefCell<Cache>>) -> Self

Creates a new CacheView from a cache handle.

pub fn borrow(&self) -> Ref<'_, Cache>

Borrows the cache immutably.

Panics

Panics if the cache is already mutably borrowed.
