    active: boolean

    use .level = LogLevel.off or LogLevel.all

    assert: (condition: unknown, ...messages: any[]) => asserts condition

    Throws if condition is not truthy.

    Attention! Due to a bug in typescript you will need to explicitly set the LoggerInterface type in order to have the assertions having an effect on unreachable code. Example:

    const log: LoggerInterface = Logger('xxx')

    debug: (...messages: any[]) => void
    error: (...messages: any[]) => void
    extend: (prefix: string) => LoggerInterface
    factory?: LoggerContextInterface
    fatal: (...messages: any[]) => never

    Always throws.
