Implementations

impl StsError

pub fn is_retryable(&self) -> bool

Returns true if the error is potentially recoverable by retrying.

Retryable errors include:

• Network/HTTP errors (timeouts, connection issues)
• Server errors (5xx)

Non-retryable errors include:

• Authentication/credential errors
• Validation errors
• Client errors (4xx except 429)

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

Returns the request ID if this is an API error.

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

Returns the error code if this is an API error.

Trait Implementations

impl Debug for StsError

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

Formats the value using the given formatter.

impl Display for StsError

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

Formats the value using the given formatter.

impl Error for StsError

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<Error> for StsError

fn from(source: Error) -> Self
