    /// Constructs a fluent builder for the [`ModifyCustomDBEngineVersion`](crate::operation::modify_custom_db_engine_version::builders::ModifyCustomDBEngineVersionFluentBuilder) operation.
    ///
    /// - The fluent builder is configurable:
    ///   - [`engine(impl Into<String>)`](crate::operation::modify_custom_db_engine_version::builders::ModifyCustomDBEngineVersionFluentBuilder::engine) / [`set_engine(Option<String>)`](crate::operation::modify_custom_db_engine_version::builders::ModifyCustomDBEngineVersionFluentBuilder::set_engine): <p>The DB engine. The only supported value is <code>custom-oracle-ee</code>.</p>
    ///   - [`engine_version(impl Into<String>)`](crate::operation::modify_custom_db_engine_version::builders::ModifyCustomDBEngineVersionFluentBuilder::engine_version) / [`set_engine_version(Option<String>)`](crate::operation::modify_custom_db_engine_version::builders::ModifyCustomDBEngineVersionFluentBuilder::set_engine_version): <p>The custom engine version (CEV) that you want to modify. This option is required for RDS Custom for Oracle, but optional for Amazon RDS. The combination of <code>Engine</code> and <code>EngineVersion</code> is unique per customer per Amazon Web Services Region.</p>

Valid values are as follows:</p>  <dl>   <dt>   available  </dt>   <dd>    <p>You can use this CEV to create a new RDS Custom DB instance.</p>   </dd>   <dt>   inactive  </dt>   <dd>    <p>You can create a new RDS Custom instance by restoring a DB snapshot with this CEV. You can't patch or create new instances with this CEV.</p>   </dd>  </dl>  <p>You can change any status to any status. A typical reason to change status is to prevent the accidental use of a CEV, or to make a deprecated CEV eligible for use again. For example, you might change the status of your CEV from <code>available</code> to <code>inactive</code>, and from <code>inactive</code> back to <code>available</code>. To change the availability status of the CEV, it must not currently be in use by an RDS Custom instance, snapshot, or automated backup.</p>
