Enum Error 

#[non_exhaustive]
pub enum Error {
    Api(Box<ApiError>),
    Transport(Error),
    NoCredentials,
    Credentials(String),
    Config(String),
    InvalidRequest(String),
    Decode(String),
    NotDone(String),
}

What a call, or waiting on an operation, failed with.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Api(Box<ApiError>)

The API refused the call, or the operation failed: branch on ApiError::reason.

Transport(Error)

The call got no answer: the connection failed or broke off.

NoCredentials

Neither the environment nor a CLI session holds credentials.

Credentials(String)

The credentials couldn’t supply an access token.

Config(String)

The client’s configuration is invalid.

InvalidRequest(String)

The request can’t be sent as it is, such as a name of the wrong form; it was not sent.

Decode(String)

The answer couldn’t be read.

NotDone(String)

Operation::result of an operation that isn’t done.

Implementations

impl Error

pub fn api(&self) -> Option<&ApiError>

The refusal, when the API refused the call or the operation failed.

pub fn reason(&self) -> Option<&str>

The platform’s error code, such as NOT_FOUND, when the API refused the call with one.

pub fn is_retryable(&self) -> bool

Whether the API answered that the same call may succeed if it is sent again.

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)>

Returns 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, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<ApiError> for Error

fn from(e: ApiError) -> Self

Converts to this type from the input type.
