Method instance

crates/wasmtime/src/runtime/linker.rs:650–673

Convenience wrapper to define an entire [`Instance`] in this linker. This function is a convenience wrapper around [`Linker::define`] which will define all exports on `instance` into this linker. The module name for each export is `module_name`, and the name for each export is the name in the instance itself. Note that when this API is used the [`Linker`] is no longer compatible with multi-[`Sto
