The delete_bucket_tagging interface deletes the tag information of a specified bucket. This article explains how to delete bucket tags using the delete_bucket_tagging interface of the Rust SDK.

Notes

You need to fill in the region and access domain in the sample code according to your actual situation. For details, see Regions and endpoints.

To prevent key leakage, the sample code reads Access Key ID and Secret Access Key from environment variables. Therefore, before using the SDK, you need to configure long-term access credentials. For details, see Configure long-term access credentials.

The operation returns 204 No Content upon success.

Permissions required

The Volcano Engine primary account has all permissions by default, but IAM users have no permissions by default. If you need to perform the delete_bucket_tagging operation using a sub-account, the Volcano Engine primary account must grant the following permissions to the sub-account through IAM policies and Bucket policies:

tos:PutBucketTagging
