Method debug_tag

crates/wasmtime/src/runtime/debug.rs:328–334

Get access to a tag within this instance's tag index space. This permits accessing tags whether they are exported or not. However, it is only available for purposes of debugging, and so is only permitted when `guest_debug` is enabled in the Engine's configuration. The intent of the Wasmtime API is to enforce the Wasm type system's encapsulation even in the host API, except where necessary for dev

    /// engine configuration for this Store.
