Struct rs_firebase_admin_sdk::GcpCredentials

pub struct GcpCredentials { /* private fields */ }

Authentication manager is responsible for caching and obtaining credentials for the required scope

Construct the authentication manager with AuthenticationManager::new() or by creating a CustomServiceAccount, then converting it into an AuthenticationManager using the From impl.

Implementations

impl AuthenticationManager

pub async fn new() -> impl Future<Output = Result<AuthenticationManager, Error>>

Finds a service account provider to get authentication tokens from

Tries the following approaches, in order:

1. Check if the GOOGLE_APPLICATION_CREDENTIALS environment variable if set; if so, use a custom service account as the token source.
2. Look for credentials in .config/gcloud/application_default_credentials.json; if found, use these credentials to request refresh tokens.
3. Send a HTTP request to the internal metadata server to retrieve a token; if it succeeds, use the default service account as the token source.
4. Check if the gcloud tool is available on the PATH; if so, use the gcloud auth print-access-token command as the token source.

pub async fn get_token( &self, scopes: &[&str] ) -> impl Future<Output = Result<Token, Error>>

Requests Bearer token for the provided scope

Token can be used in the request authorization header in format “Bearer {token}”

pub async fn project_id(&self) -> impl Future<Output = Result<String, Error>>

Request the project ID for the authenticating account

This is only available for service account-based authentication methods.

fn from(service_account: CustomServiceAccount) -> AuthenticationManager

Converts to this type from the input type.
