Enum Backend 

pub enum Backend {
    Cpu,
    Cuda,
    Metal,
}

Compute backend for the expensive numeric inner loops (constant fitting).

Variants

Cpu

CPU (always available; exact f64).

Cuda

NVIDIA CUDA GPU (requires the gpu-cuda feature and a device at runtime; falls back to CPU otherwise). Single-precision coarse fit, refined to f64 by the CPU LM polish.

Metal

Apple Metal GPU (requires the gpu-metal feature and a Metal device at runtime; falls back to CPU otherwise, macOS only). Single-precision coarse forward; exact f64 stays on the CPU.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Backend

impl Debug for Backend

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

Formats the value using the given formatter.

impl Default for Backend

fn default() -> Backend

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Backend

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Backend

impl PartialEq for Backend

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

impl Serialize for Backend

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
