pub enum ShareCapability {
Shared,
PerScenario,
PerPhase,
PerFiber,
}Expand description
Strongest sharing the resource type can tolerate.
Declared by the factory at registration time so the pool
can plan the entry layout without configuring or
instantiating any resource. The live instance’s
SharedResource::can_share is a runtime safety net
that aborts the session if it disagrees with this
type-level declaration.
The variants order from most-shared to most-isolated;
PartialOrd semantics let the pool check policy ≥
capability with a single comparison.
Variants§
Safe to share one instance across every adapter shell in the workload that produces an equal key. CQL, HTTP-with-pool, OpenAPI typically.
PerScenario
One instance per scenario subtree. Use when state changes during the run that mustn’t bleed across scenarios (auth tokens, schema versions per scenario).
PerPhase
One instance per phase. Use when each phase legitimately wants a fresh state object.
PerFiber
One instance per fiber. Use only when the resource
type is Send but not Sync, or when the
underlying library mandates single-threaded use.
