Enum GtCacheRef 

pub enum GtCacheRef<'a, T: ?Sized> {
    Borrowed(&'a T),
    Owned(Arc<T>),
}

Either a borrowed or Arc-owned reference to a per-kernel GT cache.

The borrowed variant feeds the one-shot batch entry points (evaluate_boundary_cached, evaluate_segm_cached) where the cache’s lifetime trivially exceeds the call. The Arc variant feeds the streaming substrate (crate::stream::StreamingEvaluator), where the kernel lives on a worker thread that needs 'static and the cache is the same Arc the FFI crate::CocoDataset handle holds (ADR-0020).

Variants

Borrowed(&'a T)

Caller-owned cache passed by reference; lifetime tied to the borrow. Used by the batch entry points.

Owned(Arc<T>)

Atomically refcounted cache, shared with the FFI CocoDataset handle (ADR-0020). Used by streaming so the kernel can be 'static.

Implementations

impl<T: ?Sized> GtCacheRef<'_, T>

pub fn get(&self) -> &T

Borrow the underlying cache irrespective of variant.

Trait Implementations

impl<'a, T: Clone + ?Sized> Clone for GtCacheRef<'a, T>

fn clone(&self) -> GtCacheRef<'a, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
