租借规范

注意 ：租借在 API v2 中为可选项，我们建议改用 CheckAvailabilty。

创建租借是预订的第一步。合作伙伴后端会验证请求的预约空档是否有效且仍然可用。在内部，合作伙伴会为请求的空档创建一个临时保全，并将其设置为于 lease_expiration_time自动过期。如果请求的租借时间过长，系统会允许在后端修改 lease_expiration_time。创建的租借会返回给客户端。

// Temporary lease for an inventory slot
message Lease {
  // ID of the lease. Ignored when creating a lease.

  // ID of the merchant for the slot
  string merchant_id = 2;

  // ID of the merchant service
  string service_id = 3;

  // Start time of the appointment slot

  // Duration of the appointment slot
  google.protobuf.Duration duration = 5;
