Struct CognitoIdentityCredentialProvider 

pub struct CognitoIdentityCredentialProvider { /* private fields */ }

Cognito Identity Credentials Provider

This provider fetches temporary AWS credentials using Amazon Cognito Identity. It’s typically used for mobile and web applications that need temporary AWS access.

Requirements

• A Cognito Identity Pool ID
• Optional: Identity token from a supported identity provider (Facebook, Google, etc.)

Environment Variables

The provider supports the following environment variables:

• AWS_COGNITO_IDENTITY_POOL_ID: The Cognito Identity Pool ID
• AWS_COGNITO_IDENTITY_ID: A specific identity ID (if already known)
• AWS_REGION or AWS_DEFAULT_REGION: The AWS region
• AWS_COGNITO_ENDPOINT: Custom endpoint (for testing)

Usage

use reqsign_aws_core::CognitoIdentityCredentialProvider;

let provider = CognitoIdentityCredentialProvider::new()
    .with_identity_pool_id("us-east-1:12345678-1234-1234-1234-123456789012")
    .with_region("us-east-1");
