Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. puddle.NewPool initializes a type-parameterized resource pool with constructor and MaxSize config
  2. pool.Acquire creates and leases a resource handle whose Value is accessible and increments AcquiredResources
  3. resource.Release returns the resource to the pool making it available as an idle resource
  4. resource.Destroy removes the resource from the pool invoking the Destructor callback
  5. pool.Close closes the pool and causes subsequent Acquire calls to return ErrClosedPool
