Struct OldProviders 

pub struct OldProviders {
    pub crdt_kinds: HashMap<CrdtKind, Arc<dyn CrdtKindProvider>>,
    pub logical_type_names: Vec<SmolStr>,
    pub logical_types: HashMap<SmolStr, Arc<dyn LogicalTypeProvider>>,
}

Pre-swap snapshot of the old plugin’s stateful providers.

The host populates this immediately before evicting the old plugin from the registry so the dispatcher’s schema-compat checks have the old providers to compare against. The vectors are keyed by the same names the registry uses (CrdtKind for CRDTs, extension name() for logical types).

Fields

crdt_kinds: HashMap<CrdtKind, Arc<dyn CrdtKindProvider>>

CRDT kind providers the old plugin owned, keyed by kind.

logical_type_names: Vec<SmolStr>

Names of logical types the old plugin owned (preserves order).

logical_types: HashMap<SmolStr, Arc<dyn LogicalTypeProvider>>

Logical type providers keyed by extension name.
