Report Rsassy build and CPU feature information

Returns diagnostic information about the selected Rsassy backend. Calling this initializes the native backend if it has not already been loaded. rsassy_selected_backend reports the runtime-selected backend. rsassy_installed_backends is a character vector of backend libraries found in the package installation, and rsassy_supported_backends is the subset supported by the current CPU/runtime. With "auto" selection, Rsassy chooses the best supported installed backend: AVX-512 before AVX2 on x86_64, NEON on arm64, WebAssembly SIMD128 on wasm, and scalar otherwise. The selected_* fields describe the loaded Rust backend. The cpu_* fields are detected by the C shim.

Usage

sassy_features()

Value

A sassy_features list of build, selected-backend, and CPU/runtime feature values.

Examples

sassy_features()
#> <sassy_features>
