Struct cudaResourceDesc 

pub struct cudaResourceDesc {
    pub res_type: c_int,
    pub payload: [u8; 32],
    /* private fields */
}

cudaResourceDesc — tagged union describing a texture/surface source. Layout: type: i32 + 4-byte pad + 32-byte union payload + 8-byte pad. We model the union as an opaque byte buffer and expose typed builders.

Fields

res_type: c_int

payload: [u8; 32]

32 bytes — the widest union arm (pitch2D: devPtr + desc + w + h + pitch).

Implementations

impl cudaResourceDesc

pub fn from_array(array: cudaArray_t) -> Self

pub fn from_linear( dev_ptr: *mut c_void, desc: cudaChannelFormatDesc, size_in_bytes: usize, ) -> Self

Build a LINEAR-type descriptor: bytewise view of a device pointer.
