Is a GPU available

Reports whether a usable WGPU adapter is present. Every function in this package needs one, and without it the Rust side aborts rather than returning an error, so this is the way to branch before calling into it.

The probe initialises the same client the GPU functions use, so a TRUE means they will genuinely run rather than that a device merely exists. It is cached for the session, and the client is left warm, so the first real call afterwards skips the setup cost.

Usage

gpu_available()

Value

Boolean. TRUE when a WGPU adapter could be initialised.

Examples

if (gpu_available()) {
  # ... GPU path
}
#> NULL
