//! Built-in GPU kernels that ship with prgpu.
//!
//! Each kernel splits into two pieces:
//! 1. `<name>_struct.rs` defines the `<Name>Params` constant-buffer struct
//!    + `KernelParams` impl. Private to this module.
//! 2. `mod.rs` (this file) re-exports the struct and wires the dispatch
//!    module with `__kernel_dispatch_externs!`.
