Implementations

impl DukascopyError

pub fn is_retryable(&self) -> bool

Returns true if this error is retryable.

Retryable errors are transient and may succeed on retry:

• Rate limiting
• Timeouts
• Some HTTP errors

pub fn is_not_found(&self) -> bool

Returns true if this error indicates the data doesn’t exist.

pub fn is_validation_error(&self) -> bool

Returns true if this error is due to invalid input.

pub fn is_configuration_error(&self) -> bool

Returns true if error is caused by client configuration.

Trait Implementations

impl Clone for DukascopyError

fn clone(&self) -> DukascopyError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DukascopyError

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

Formats the value using the given formatter.

impl Display for DukascopyError

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

Formats the value using the given formatter.

impl Error for DukascopyError

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.
