Struct AzureAuth 

pub struct AzureAuth { /* private fields */ }

Azure authentication handler that manages credentials and token caching.

Implementations

impl AzureAuth

pub fn new(api_key: Option<String>) -> Result<Self, AuthError>

Creates a new Azure authentication handler.

Initializes the authentication handler by:

1. Loading credentials from environment
2. Setting up an HTTP client for token requests
3. Initializing the token cache

Returns

• Result<Self, AuthError> - A new AzureAuth instance or an error if initialization fails

pub fn credential_type(&self) -> &AzureCredentials

Returns the type of credentials being used.

pub async fn get_token(&self) -> Result<AuthToken, AuthError>

Retrieves a valid authentication token.

This method implements an efficient token management strategy:

1. For API key auth, returns the API key directly
2. For Azure credential chain: a. Checks the cache for a valid token b. Returns the cached token if not expired c. Obtains a new token if needed or expired d. Uses double-checked locking for thread safety

Returns

• Result<AuthToken, AuthError> - A valid authentication token or an error
