Detailed Description

Representation of a WebAssembly value.

Note that this structure is intended to represent the way to communicate values from the embedder to the engine. This type is not actually the internal representation in JIT code, for example.

Also note that this is an owned value, notably the ref field. The wasm_val_delete function does not delete the memory holding the wasm_val_t itself, but only the memory pointed to by wasm_val_t.

The documentation for this struct was generated from the following files:
