Struct CUgraphNodeParams 

#[repr(C)]
pub struct CUgraphNodeParams {
    pub type_: c_int,
    pub reserved0: [c_int; 3],
    pub payload: [u64; 29],
    pub reserved2: c_longlong,
}

CUgraphNodeParams — generic node-params tagged union. We model the payload as an opaque [u64; 30] (large enough to hold any variant) plus the discriminant and tail. Safe wrappers populate the payload via typed helpers; raw users can cast through payload.as_mut_ptr().

Layout (CUDA 13.x):

struct CUgraphNodeParams {
    CUgraphNodeType type;     // 4
    int reserved0[3];         // 12
    union { ... } payload;    // 232 bytes (29 × c_longlong)
    long long reserved2;      // 8
};

Total 256 bytes, alignment 8.

Fields

type_: c_int

reserved0: [c_int; 3]
