//! GPU weight cache — uploads model weights once, reuses across all GEMV/GEMM calls.
//!
//! The [`GpuWeightHandle`] is a lightweight, copyable identifier that references
//! a weight buffer resident on GPU memory. Weights are uploaded once via the
//! [`OneBitKernel::upload_weights`](crate::traits::OneBitKernel::upload_weights)
//! method and reused for all subsequent inference calls, eliminating costly
//! host→device copies on every token.

/// Opaque handle referencing a weight buffer resident on GPU memory.
///
/// Cheap to clone (just a `u64` ID). Works even without the `gpu` feature —
/// in that case it's simply a marker that the non-GPU kernel ignores.
