Detailed Description

A WebAssembly exception reference value.

This structure represents an exnref value, which is a reference to a WebAssembly exception object. Like other GC reference types, it must be explicitly unrooted via wasmtime_exnref_unroot to enable garbage collection.

Null exnref values are represented with store_id == 0.
