Classes 7

CCellOutResult of a single-cell read. CCellSnapshotResolved values of a sparse coordinate batch, one entry per requested cell. CCellStoreThe workbook-wide store: every sheet, one string pool. CDistinctColumnDistinct-value scan result for one column: parallel kind/number/text arrays whose buffers are surrendered once through the take accessors. CRangeSnapshotOpaque, store-local history payload for one dense rectangular cell block. CSourceSnapshotCompact serializable projection of persisted derived-cell sources and spill identity in one range. CWindowViewA bulk window of resolved cells, row-major over nrows x ncols.

Functions 5

FcreateEngineInitialize a fresh engine; a compiled module can be reused without retaining its memory. FfunctionNamesNames accepted by the full engine, including aliases. FinitSyncInstantiates the given module, which can either be bytes or a precompiled WebAssembly.Module. FisLoadedWhether the WASM module has finished initializing. FloadInitialize the WASM module.

Interfaces 1

IInitOutputResult of module initialization: the instantiated exports plus the shared linear memory.

Types 3

TEngineInstanceEngine objects and caches owned by one independently collectible WASM instance. TInitInputSources accepted by asynchronous initialization: a fetchable URL/request/response, raw module bytes, or a precompiled WebAssembly.Module. TSyncInitInputSources accepted by synchronous initialization: raw module bytes or a precompiled WebAssembly.Module.
