//! These are the raw HTTP operations with correct URLs, methods,
//! and parameter ordering. The hand-written `api/cloudbilling.rs` wraps
//! these with ergonomic builders, operation polling, etc.

    /// [billing account](https://cloud.google.com/billing/docs/how-to/billing-access). You can

    /// This action disassociates the current billing account from the project. Any billable
    /// activity of your in-use services will stop, and your application could stop functioning
    /// as expected. Any unbilled charges to date will be billed to the previously associated
    /// account. The current authenticated user must be either an owner of the project or an
    /// owner of the billing account for the project. Note that associating a project with a
    /// *closed* billing account will have much the same effect as disabling billing on the
    /// project: any paid resources used by the project will be shut down. Thus, unless you wish
    /// to disable billing, you should always call this method with the name of an *open*
