Variants

NoAuthMethod(Box<Error>, Box<Error>, Box<Error>)

No available authentication method was discovered

Application can authenticate against GCP using:

• Default service account - available inside GCP platform using GCP Instance Metadata server
• GCloud authorized user - retrieved using gcloud auth command

All authentication methods have been tested and none succeeded. Service account file can be downloaded from GCP in json format.

TlsError(Error)

Error in underlying RustTLS library. Might signal problem with establishing secure connection using trusted certificates

OAuthConnectionError(Error)

Error when establishing connection to OAuth server

CustomServiceAccountPath(Error)

Wrong path to custom service account credentials provided

By default, the custom service account credentials are parsed from the path pointed to by the GOOGLE_APPLICATION_CREDENTIALS environment variable.

CustomServiceAccountCredentials(Error)

Failed to parse the application credentials provided

By default, the custom service account credentials are parsed from the path pointed to by the GOOGLE_APPLICATION_CREDENTIALS environment variable.

UserProfilePath(Error)

Default user profile not found

User can authenticate locally during development using gcloud auth login which results in creating ~/.config/gcloud/application_default_credentials.json which couldn’t be find on the machine

UserProfileFormat(Error)

Wrong format of user profile

ConnectionError(Error)

Could not connect to server

ParsingError(Error)

Could not parse response from server

ServerUnavailable(String)

Could not connect to server

SignerFailed

Could not sign requested message

SignerInit

Could not initialize signer

NoHomeDir

Could not find Home directory in the environment

NoProjectId

Project ID not supported for current authentication method

ProjectIdNotFound

Project ID not found through current authentication method

ProjectIdNonUtf8

Project ID is invalid UTF-8

GCloudNotFound

GCloud executable not found

GCloudError

GCloud returned an error status

GCloudParseError

GCloud output couldn’t be parsed

IOError(Error)

Represents all other cases of std::io::Error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
