Enum ExecPolicy 

pub enum ExecPolicy {
    Sequential,
    Parallel(usize),
}

Per-call execution policy for a compute backend operation.

Parallel(0) means “backend auto” — faer uses rayon’s current_num_threads, while HPTT resolves 0 via std::thread::available_parallelism() before crossing the FFI boundary (HPTT 0.4 rejects a literal 0). Parallel(n) with n > 0 is a target worker count whose strictness depends on the backend: HPTT spawns exactly n OpenMP threads, while faer and the naive Rayon kernel treat n as a partitioning hint dispatched on the global Rayon pool. Sequential forces single-threaded execution.

Variants

Sequential

Force single-threaded execution.

Parallel(usize)

Run in parallel with the given target worker count; 0 means “backend auto” (see the type-level note for per-backend semantics).

Trait Implementations

impl Clone for ExecPolicy

fn clone(&self) -> ExecPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ExecPolicy

impl Debug for ExecPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ExecPolicy

impl PartialEq for ExecPolicy

fn eq(&self, other: &ExecPolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
