# Service Credential Module
IAM service-specific credential resource management for WAMI. This module provides
strongly typed representations, builders, and request types for managing
service-specific credentials used by AWS services like CodeCommit and IoT.
## Overview
Service-specific credentials are long-term credentials generated for specific AWS
services that don't support regular access keys. This module provides:
- **Model Types** – `ServiceSpecificCredential` and `ServiceSpecificCredentialMetadata`
for representing service credential resources
- **Builder Functions** – Context-aware builders that generate consistent WAMI ARNs
- **Request Types** – DTOs for service API operations
## Models
### `ServiceSpecificCredential`
Represents a service-specific credential with the following fields:
- `user_name` – The IAM user associated with the credential
- `service_specific_credential_id` – Unique identifier for the credential
- `service_user_name` – Generated username for the service
- `service_password` – Generated password (only provided during creation)
- `service_name` – Name of the service (e.g., "codecommit.amazonaws.com")
- `create_date` – Timestamp when the credential was created
- `status` – Status of the credential (`Active` or `Inactive`)
- `wami_arn` – WAMI ARN for cross-provider identification
- `providers` – List of cloud provider configurations
### `ServiceSpecificCredentialMetadata`
Metadata about a service-specific credential (without the password):
- `user_name` – The IAM user associated with the credential
- `service_specific_credential_id` – Unique identifier for the credential
- `service_user_name` – Generated username for the service
- `service_name` – Name of the service
- `create_date` – Timestamp when the credential was created
- `status` – Status of the credential
## Builder Functions
### `build_service_credential`
Creates a new `ServiceSpecificCredential` with context-based identifiers:
```rust
use wami_core::context::WamiContext;
use wami_credentials::service_credential::build_service_credential;
let context = WamiContext::builder()
.instance_id("123456789012")
.tenant_path(wami_core::arn::TenantPath::single(0))
.caller_arn(/* ... */)
.build()
.unwrap();
let credential = build_service_credential(
"alice".into(),
"codecommit.amazonaws.com".into(),
&context,
)?;
```
## Request Types
The module provides request and response types for service credential operations:
- `CreateServiceSpecificCredentialRequest` – Request to create a service credential
- `CreateServiceSpecificCredentialResponse` – Response containing the created credential with password
- `ListServiceSpecificCredentialsRequest` – Request to list service credentials for a user
- `ListServiceSpecificCredentialsResponse` – Response containing a list of credential metadata
- `UpdateServiceSpecificCredentialRequest` – Request to update credential status
- `DeleteServiceSpecificCredentialRequest` – Request to delete a service credential
- `ResetServiceSpecificCredentialRequest` – Request to reset a credential's password
- `ResetServiceSpecificCredentialResponse` – Response containing the credential with new password
## Usage Example
```rust
use wami_core::context::WamiContext;
use wami_credentials::service_credential::build_service_credential;
use wami_credentials::ServiceSpecificCredential;
let context = WamiContext::builder()
.instance_id("123456789012")
.tenant_path(wami_core::arn::TenantPath::single(0))
.caller_arn(
wami_core::arn::WamiArn::builder()
.service(wami_core::arn::Service::Iam)
.tenant(0)
.wami_instance("123456789012")
.resource("user", "admin")
.build()
.unwrap(),
)
.is_root(false)
.build()
.unwrap();
// Create a new service-specific credential for CodeCommit
let credential = build_service_credential(
"alice".into(),
"codecommit.amazonaws.com".into(),
&context,
)?;
assert_eq!(credential.user_name, "alice");
assert_eq!(credential.service_name, "codecommit.amazonaws.com");
assert_eq!(credential.status, "Active");
assert!(credential.service_password.is_some()); // Only available on creation
assert!(credential.wami_arn.to_string().contains("service-credential"));
```
