Enum RandomKind 

#[non_exhaustive]
#[repr(u16)]
pub enum RandomKind {
    Uniform = 0,
    Normal = 1,
    Bernoulli = 2,
    Multinomial = 3,
}

Random / sampling op discriminant.

Stored as u16 in crate::KernelSku::op when category == OpCategory::Random. Phase 4.5 wires:

• Self::Uniform (f32, f64) — y ~ U(low, high) via cuRAND.
• Self::Normal (f32, f64) — y ~ N(mean, std) via cuRAND.
• Self::Bernoulli (Bool output) — y = (rand < p) ? 1 : 0 via cuRAND uniform + custom threshold kernel.

Multinomial / Randint / exponential / gamma / quasi-random are reserved discriminants for future milestones.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Uniform = 0

y[i] ~ U(low, high) — uniform on the half-open interval. Plan descriptor param1 = low, param2 = high.

Normal = 1

y[i] ~ N(mean, std) — Gaussian. Plan descriptor param1 = mean, param2 = stddev.

Bernoulli = 2

y[i] = 1 if uniform < p else 0, Bool output. Plan descriptor param1 = p. param2 ignored.

Multinomial = 3

y[b] = sample one cell from row probs[b, :] using inverse-CDF sampling. Phase 46 wires the FlashInfer sort-free Top-K / Top-P / Min-P / combined Top-K + Top-P samplers under this discriminant via the TopKTopPSamplingPlan in baracuda-kernels.

Trait Implementations

impl Clone for RandomKind

fn clone(&self) -> RandomKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RandomKind

impl Debug for RandomKind

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

Formats the value using the given formatter.

impl Eq for RandomKind

impl Hash for RandomKind

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 RandomKind

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