Implementations

impl GatewayError

pub fn status_code(&self) -> StatusCode

Returns HTTP status code for this error.

pub fn is_retryable(&self) -> bool

Returns whether this error is retryable.

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

Returns retry-after duration in seconds if applicable.

pub fn to_json_response(&self) -> Value

Converts error to JSON error response.

pub fn error_code(&self) -> &str

Returns error code string.

Trait Implementations

impl Debug for GatewayError

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

Formats the value using the given formatter.

impl Display for GatewayError

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

Formats the value using the given formatter.

impl Error for GatewayError

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 GatewayError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for GatewayError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<GatewayError> for StatusCode

fn from(error: GatewayError) -> Self

Converts to this type from the input type.
