Struct RulePackSnapshot 

pub struct RulePackSnapshot {
    pub index: Arc<DashMap<String, IndexedDoc>>,
    pub packs: Arc<Vec<RulePack>>,
    pub seq: u64,
}

An immutable, cheaply-cloneable snapshot of the workspace index at a specific moment in time.

Analogous to rust-analyzer’s GlobalStateSnapshot: takes an Arc clone of the index so async scan tasks can hold a stable view of the workspace even as documents continue to be edited.

Why snapshots instead of locking

If a background rule evaluation held a MutexGuard over the workspace index while scanning, every did_change notification would block until the scan completed. By cloning Arc<DashMap<...>> into a snapshot we pay only the cost of incrementing an atomic reference count — O(1) regardless of workspace size.

Fields

index: Arc<DashMap<String, IndexedDoc>>

A frozen view of the workspace index at snapshot time.

packs: Arc<Vec<RulePack>>

The composed packs active at snapshot time.

seq: u64

A logical sequence number incremented on every mutation to the index. Consumers can use this to detect staleness.
