Module curand 

Thin Rust-level wrappers over [cudarc::curand::sys] for the cuRAND host-API entry points that aren’t surfaced by the safe [cudarc::curand::CudaRng] handle:

• generator creation by explicit curandRngType_t (Philox4_32_10, XORWOW, MTGP32, MRG32K3A, plus all four Sobol variants);
• the host-API generator pair (curandCreateGeneratorHost — fills host buffers, copies internally);
• curandSetQuasiRandomGeneratorDimensions, curandSetGeneratorOrdering, curandSetGeneratorOffset;
• the Poisson and bit-generator families (curandGeneratePoisson, curandGenerate, curandGenerateLongLong).

These functions are unsafe — they take the raw curandGenerator_t and require the caller to keep the generator alive, valid, and bound to a stream that the destination pointer lives on. The actor in kernel/rng/* is the only intended caller.

Enums

RngGeneratorKind

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.

Functions

create_generator^⚠

Create a device-side generator of the given kind (curandCreateGenerator).

destroy_generator^⚠

curandDestroyGenerator.

generate_poisson_u32^⚠

curandGeneratePoisson — fill out with n u32 values drawn from a Poisson distribution parameterised by lambda (f64).

generate_u32^⚠

curandGenerate — raw u32 bit fill (used as the building block for any custom transform).

generate_u64^⚠

curandGenerateLongLong — raw u64 bit fill.

set_offset^⚠

curandSetGeneratorOffset.

set_seed^⚠

curandSetPseudoRandomGeneratorSeed.

set_stream^⚠

Bind gen to stream (curandSetStream).
