Struct IamProvider 

pub struct IamProvider { /* private fields */ }

Exchanges temporary AWS credentials for short-lived Redshift cluster credentials via redshift:GetClusterCredentials.

Implementations

impl IamProvider

pub fn new( user: impl ToString, database: impl ToString, cluster: impl ToString, autocreate: bool, ) -> Self

Creates a new IamProvider.

• autocreate: When true, the Redshift user is created automatically if it does not already exist.
• The AWS region defaults to "us-east-1"; change it with set_region.

Examples

use redshift_iam::IamProvider;
let iam = IamProvider::new("alice", "analytics", "my-cluster", false);
assert_eq!(iam.region(), "us-east-1");

pub fn set_region(self, region: impl ToString) -> Self

Overrides the AWS region used when calling GetClusterCredentials.

Examples

use redshift_iam::IamProvider;
let iam = IamProvider::new("alice", "analytics", "my-cluster", false)
    .set_region("eu-west-1");
assert_eq!(iam.region(), "eu-west-1");

pub fn region(&self) -> String

Returns the configured AWS region.

pub fn auth(&self, aws_credentials: Credentials) -> (String, String)

Calls redshift:GetClusterCredentials with the provided AWS credentials and returns a (username, password) pair valid for 3600 seconds.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
