Select the Rsassy native backend — sassy_set

Select a backend for the current R process. Backend loading is intentionally one-shot: the selected shared library is fixed for the lifetime of the R process. This must be called before the first native Rsassy operation, including sassy_features(), sassy_searcher(), or sassy_search(). Rsassy does not unload and replace backend DLLs because that is not reliable across R platforms. Use this for benchmarking installed backends against each other in separate fresh R processes.

Usage

sassy_set_backend(
  backend = c("auto", "scalar", "avx2", "avx512", "neon", "wasm_simd128")
)

Arguments

backend: One of "auto", "scalar", "avx2", "avx512", "neon", or "wasm_simd128".

Value

The requested backend name, invisibly. "auto" means runtime dispatch will choose the best installed backend supported by the current CPU/runtime when the backend is first loaded.
