Crate rustkernel_derive 

Procedural macros for RustKernels.

This crate provides the following macros:

• #[gpu_kernel] - Define a GPU kernel with metadata
• #[derive(KernelMessage)] - Derive serialization for kernel messages
• #[kernel_state] - Mark types as GPU-compatible kernel state

For low-level ring kernel macros, see ringkernel-derive 0.4.2 which provides:

• #[derive(RingMessage)] - Ring message serialization with domain-based type IDs
• #[derive(PersistentMessage)] - CUDA persistent message dispatch
• #[derive(ControlBlockState)] - Embedded state for GPU ControlBlocks
• #[derive(GpuType)] - Pod+Zeroable for GPU data transfer
• #[ring_kernel] - Ring kernel handler generation
• #[stencil_kernel] - CUDA stencil pattern kernels

Example

use rustkernel_derive::gpu_kernel;

#[gpu_kernel(
    id = "graph/pagerank",
    mode = "ring",
    domain = "GraphAnalytics",
    throughput = 100_000,
    latency_us = 1.0
)]
pub async fn pagerank_kernel(
    ctx: &mut RingContext,
    request: PageRankRequest,
) -> PageRankResponse {
    // Implementation
}
