pub trait KeyedSingletonSnapshotBound: KeyedSingletonBound + Sealed { }Expand description
Marker trait for the KeyedSingletonBound types that support
KeyedSingleton::snapshot: those whose entries may change over time (Unbounded,
MonotonicKeys, MonotonicValue) and fully Bounded keyed singletons (whose
complete contents are observed on every tick).
BoundedValue is excluded: each of its entries is final once it appears, so it is windowed
into a tick with KeyedSingleton::batch, which observes just the new entries.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
