Enum ExecutionPolicy 

pub enum ExecutionPolicy {
    CpuSingle,
    CpuParallel,
    Gpu(DeviceKind),
    Auto,
}

Execution policy for spatial algorithms.

Variants

CpuSingle

Single-threaded CPU execution.

CpuParallel

Parallel CPU execution.

Gpu(DeviceKind)

GPU execution on a device of the given kind.

Auto

Automatic selection based on runtime heuristics.

Implementations

impl ExecutionPolicy

pub fn validate(self) -> Result<(), SpatialError>

Validates that the policy names a meaningful execution request.

pub const fn is_explicit(self) -> bool

Returns whether the policy names a concrete execution backend.

pub const fn requests_gpu(self) -> bool

Returns whether the policy requests an accelerator backend.

pub const fn allows_fallback(self) -> bool

Returns whether the policy lets an algorithm choose a fallback backend.

Auto is the only policy with fallback semantics. An explicit CPU or GPU policy is a request for that backend and must be reported as unsupported when the backend cannot satisfy it.

pub const fn device_kind(&self) -> Option<DeviceKind>

Returns the device kind targeted by this policy when known.

Trait Implementations

impl Clone for ExecutionPolicy

fn clone(&self) -> ExecutionPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionPolicy

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

Formats the value using the given formatter.

impl Default for ExecutionPolicy

fn default() -> ExecutionPolicy

Returns the “default value” for a type.

impl Hash for ExecutionPolicy

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExecutionPolicy

fn eq(&self, other: &ExecutionPolicy) -> 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.
