Struct WasmProcedure 

pub struct WasmProcedure { /* private fields */ }

WASM procedure that loads and executes a .wasm module.

Each WASM module must export:

• alloc(size: i32) -> i32 — allocate size bytes, return pointer
• dealloc(ptr: i32, size: i32) — free memory
• procedure(params_ptr: i32, params_len: i32) -> i32 — pointer to output (first 4 bytes at output pointer = output length as LE u32)
