get_bucket_info 接口用于查询存储桶配置信息，本文介绍如何通过 Rust SDK 的 get_bucket_info 接口获取名称、地域、存储类型、加密规则等完整元数据。

注意事项

您需要根据实际情况，填写示例代码中的地域和访问域名，详细介绍，请参见地域和访问域名。

为了防止密钥泄露，本文示例代码需要从环境变量中读取 Access Key ID 和 Secret Access Key。因此使用 SDK 前，您需要配置长期访问凭证，详细介绍，请参见配置长期访问凭证。

权限说明

火山引擎主账号默认拥有全部权限，但是 IAM 用户默认没有任何权限。如果您需要使用子账号执行 get_bucket_info 操作，火山引擎主账号需通过 IAM策略和桶策略为该子账号授予以下权限：

tos:GetBucketInfo
