func Do ¶

func Do(parent context.Context, fn func(ctx context.Context)) error

Do executes a function in a "Critical Section" that delays context cancellation. It wraps the provided function in a shielded context that ignores the parent's cancellation. The shielded context is only cancelled AFTER the function finishes or the parent is cancelled AND a reasonable grace period has passed (optional, for now it just shields until finish).
