Going from AssumeRoleProvider to Credentials

[lcmgh]

Hi!

To make it much easier to connect to RDS databases I am working on a command line user interface that

• auto detects bastion hosts for RDS clusters (based on tag matching)
• lists rds clusters
• establishes tunnel via aws cli ssm + ssh (and remembers the port it used the last time for a certain connection)

Next I want to make the app generate temporary access tokens for databases that support IAM based authentication and then spawn a db client (psql, dbeaver etc.) that auto-establishes the connection.

For generating the temporary password I am usnig this code: https://docs.rs/aws-sig-auth/0.55.1/aws_sig_auth/#generate-rds-iam-token

However I am facing an issue that I have described here: https://github.com/awslabs/aws-sdk-rust/issues/792#issuecomment-1543798866

Could you please help regarding that?

Thanks

AssumeRoleProvider implements the ProvideCredentials trait, which you can use to resolve the actual credentials:
https://docs.rs/aws-config/0.55.3/aws_config/sts/struct.AssumeRoleProvider.html#impl-ProvideCredentials-for-AssumeRoleProvider

Something like:

let credentials = provider.provide_credentials().await?;
