# CPU execution: pulls in rlx-cpu's CpuKernel registry + LAPACK dgesv.
cpu = ["dep:rlx-cpu"]

# Metal execution: pulls in rlx-metal's MetalKernel registry. Implies
# `cpu` because the kernel bodies share LAPACK `dgesv` for Sparse-LU
# (Apple Silicon ships Accelerate, so the dep is free in practice).
metal = ["dep:rlx-metal", "cpu"]

# MLX execution: pulls in rlx-mlx's MlxKernel registry. Same shared-cpu
# rationale as `metal`. Kernels read input `Array` bytes, run the host
# `algos::*` body, and rebuild an output `Array`.

# rlx-metal is an Apple-only backend (Metal is an Apple API); make it a

# the `metal` feature only pulls it where the backend exists — no non-Apple stub.
