func Ensure ¶

func Ensure(opts ...googlesql.Option) error

Ensure calls googlesql.Init(opts...) exactly once for this process. The first caller's options win; subsequent calls return the first call's error (or nil) without invoking Init again.

Workaround [go-googlesql v0.2.1]: `googlesql.Init` is itself `sync.Once`-guarded, but its return value on second-and-later calls is nil regardless of whether the first call failed, so a caller that races Init cannot observe a stable error.

Upstream C++ API: none — `googlesql.Init` is a Go-binding-only entry point that drives wazero/wasm runtime startup; there is no equivalent symbol in `google/googlesql` (the C++ library is just linked, not "initialised"). Treat this as a binding-shape bug rather than a missing C++ accessor.

Natural Go code:

if err := googlesql.Init(opts...); err != nil { ... }   // call as many times as you want

Instead, the local `sync.Once` here remembers initErr so every caller sees the same outcome. Unblocked when go-googlesql either makes Init's "already initialised" return path replay the original error, or exposes a separate `googlesql.InitError()` accessor.
