Enum RngGeneratorKind 

pub enum RngGeneratorKind {
    PseudoDefault,
    Philox4_32_10,
    XorWow,
    Mrg32K3A,
    Mtgp32,
    Sobol32,
    ScrambledSobol32,
    Sobol64,
    ScrambledSobol64,
}

Public mirror of [sys::curandRngType_t] so callers don’t have to take a cudarc::curand::sys::* symbol on their public API. The numeric values match cuRAND.

Variants

PseudoDefault

CURAND_RNG_PSEUDO_DEFAULT — XORWOW today; defined by cuRAND.

Philox4_32_10

CURAND_RNG_PSEUDO_PHILOX4_32_10. Recommended high-quality pseudo-RNG. Counter-based, friendly to SIMD/SIMT.

XorWow

CURAND_RNG_PSEUDO_XORWOW. Default in cuRAND <= 11.

Mrg32K3A

CURAND_RNG_PSEUDO_MRG32K3A. L’Ecuyer’s MRG.

Mtgp32

CURAND_RNG_PSEUDO_MTGP32. Mersenne Twister 32-bit.

Sobol32

CURAND_RNG_QUASI_SOBOL32. Quasi-random 32-bit Sobol.

ScrambledSobol32

CURAND_RNG_QUASI_SCRAMBLED_SOBOL32.

Sobol64

CURAND_RNG_QUASI_SOBOL64.

ScrambledSobol64

CURAND_RNG_QUASI_SCRAMBLED_SOBOL64.

Implementations

impl RngGeneratorKind

pub fn is_quasi(self) -> bool

Whether this kind is a quasi-random (Sobol) generator. Quasi generators must be configured with [set_quasi_random_dimensions] before any fill, and they do not accept a pseudo-random seed.

pub fn is_quasi_64(self) -> bool

64-bit Sobol vs. 32-bit Sobol. Kept separate from Self::is_quasi so callers can pick the matching curandSetQuasiRandomGeneratorDimensions argument width without re-matching.

pub fn to_sys(self) -> curandRngType_t

Trait Implementations

impl Clone for RngGeneratorKind

fn clone(&self) -> RngGeneratorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RngGeneratorKind

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

Formats the value using the given formatter.

impl Default for RngGeneratorKind

fn default() -> RngGeneratorKind

Returns the “default value” for a type.

impl Hash for RngGeneratorKind

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

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 RngGeneratorKind

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