_StorageSetup< FUN > Struct Template Reference

#include "steam/engine/feed-manifold.hpp"

Description

template<class FUN>
struct steam::engine::_StorageSetup< FUN >

Configuration context for a FeedManifold.

This type-rebinding helper provides a storage configuration specifically tailored to serve the invocation of FUN

Note

storage segments for input and parameters are only present when the given function is classified by _ProcFun<FUN> as handling input and / or parameters.

Remarks

since BuffHandle is not default-constructible, but must be retrieved from a BufferProvider rather, a chunk of uninitialised storage is used to accept the BuffHandles allocated and populated with results from preceding Nodes.
