Struct StageSpec 

pub struct StageSpec { /* private fields */ }

The blueprint description of a stage: its name, erased ports, the internal kind the executor switches on, async-boundary flag, and attributes. Construct one with StageSpec::opaque for a custom stage that runs its own GraphStageLogic; built-in stages use the crate-internal constructors.
