ServerError(String)

The server returned a 5xx error.

Timeout

Implementations

impl RestError

pub fn is_not_found(&self) -> bool

Check if this is a not found error

pub fn is_unauthorized(&self) -> bool

Check if this is an authentication error

pub fn is_server_error(&self) -> bool

Check if this is a server error

pub fn is_timeout(&self) -> bool

Check if this is a timeout error

pub fn is_rate_limited(&self) -> bool

Check if this is a rate limit error

pub fn is_conflict(&self) -> bool

Check if this is a conflict/already exists error

pub fn is_cluster_busy(&self) -> bool

Check if this is a cluster busy error

pub fn is_retryable(&self) -> bool

Check if this error is retryable

pub fn is_bad_request(&self) -> bool

Check if this is a bad request / validation error

Trait Implementations

impl Clone for RestError

fn clone(&self) -> RestError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestError

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

Formats the value using the given formatter.

impl Display for RestError

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

Formats the value using the given formatter.

impl Error for RestError

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 RestError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for RestError

fn from(err: Error) -> Self

Converts to this type from the input type.
