6  * Support for running Halide-compiled Wasm code in-process.
7  * Bindings for parameters, extern calls, etc. are established and the
8  * Wasm code is executed. Allows calls to realize to work
9  * exactly as if native code had been run, but via a JavaScript/Wasm VM.
10  * Currently, only the WABT interpreter is supported.

Defines a type used for expressing the type signature of a generated halide pipeline.
Defines the struct representing lifetime and dependencies of a JIT compiled halide pipeline.
Defines the internal representation of parameters to halide piplines.
Defines halide types.
A halide module.
