Implementations

impl FinanceError

pub fn is_retriable(&self) -> bool

Check if this error is retriable

pub fn is_auth_error(&self) -> bool

Check if this error indicates an authentication issue

pub fn is_not_found(&self) -> bool

Check if this error indicates a not found issue

pub fn retry_after_secs(&self) -> Option<u64>

Get retry delay in seconds (for exponential backoff)

pub fn category(&self) -> ErrorCategory

Categorize errors for logging/metrics

pub fn with_symbol(self, symbol: impl Into<String>) -> Self

Add symbol context to error (fluent API)

pub fn with_context(self, context: impl Into<String>) -> Self

Add context to error (fluent API)

impl FinanceError

pub fn parse_error(msg: impl Into<String>) -> Self

👎Deprecated since 2.0.0: Use ResponseStructureError instead

Create a ParseError from a string (for backward compatibility)

Trait Implementations

impl Debug for FinanceError

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

Formats the value using the given formatter.

impl Display for FinanceError

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

Formats the value using the given formatter.

impl Error for FinanceError

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.
