 Both the `Sentry.logger.X` and `Sentry.logger.emit` methods are fire-and-forget (have no return value). This means that the SDK can choose to run these methods on a separate thread or queue them up for processing later. This includes evaluating the string template, and running any internal hooks (like `beforeSendLog`). The SDK should ensure that the logs are sent in the order they are received.

This mechanism will vary by platform, and the individual SDK will need to figure out the best approach for their platform.
