pub fn rate_limit(retry_after_secs: Option<u64>) -> Self

Create a rate limit error.

pub fn context_overflow(tokens: usize) -> Self

Create a context overflow error.

pub fn invalid_response(message: impl Into<String>) -> Self

Create an invalid response error.

pub fn service_unavailable(message: impl Into<String>) -> Self

Create a service unavailable error.

pub fn json_error(message: impl Into<String>) -> Self

Create a JSON error.

pub fn network_error(message: impl Into<String>) -> Self

Create a network error.

pub fn invalid_request(message: impl Into<String>) -> Self

pub fn is_retryable(&self) -> bool

Check if this error is retryable.

Trait Implementations

impl Clone for ProviderError

fn clone(&self) -> ProviderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl Display for ProviderError

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

Formats the value using the given formatter.

impl Error for ProviderError

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.
