Module runtime 

Runtime for dispatching device functions to CPU or device.

Structs

Buffer

Opaque handle to a device-runtime buffer.

Cpu

CPU backend: mapping-expression-based interpretation.

Kernel

Device kernel loaded from a serialized binary.

Npu

NPU backend: PCIe DMA to/from device.

NpuDesc

Traits

Backend

Backend for tensor operations.

DeviceFn

Device function trait, generated by #[device] macro.

TupleApply

Trait for applying a function to arguments.

Functions

kernel_path

Builds the on-disk .bin path for a kernel, from the perspective of the #[device] macro expansion. module_path!() includes the crate name (my_crate::sub::mod), but the plugin’s artifact names use tcx.def_path_str which strips it (sub::mod); this helper drops the leading crate segment and mangles :: → __ so the stem agrees with rustc_plugin::build_one.

launch

Launches a device function. Takes F by value so callers can pass the snake_case const emitted by #[device] (launch(my_fn, args)) rather than turbofishing the generated PascalCase unit struct (<MyFn as DeviceFn<_>>::execute(args)). The value is discarded; only its type drives trait dispatch.
