Struct SnapshotSpec 

Source 
pub struct SnapshotSpec;
Expand description

Snapshot-based observation specification.

SnapshotSpec marks a type as supporting efficient snapshot comparison (requires Clone + PartialEq). When used as the Spec for a type T, it affects certain wrapper type observations, such as Option<T>.
