Configure worker threads for the Rust backend

Dynamically configures the Rayon thread pool budget in the native Rust backend. If n is omitted or NULL, the thread count is automatically determined via detect_hpc_cores().

set_hpc_threads(n = NULL)

Arguments

n

integer number of worker threads (must be >= 1). If NULL (the default), automatically detects the allocated core quota.

Value

An integer representing the newly configured thread count (invisibly).
