Struct CandidDecodeFailed

pub struct CandidDecodeFailed { /* private fields */ }

Represents an error that occurs when the response from an inter-canister call cannot be decoded as Candid.

This error type provides details about the Candid decoding failure, including the type that was being decoded and the specific Candid error that occurred.

This is the only possible error that can occur in Response::candid and Response::candid_tuple.

It is wrapped by the top-level Error::CandidDecodeFailed variant.

Trait Implementations

impl CallErrorExt for CandidDecodeFailed

fn is_clean_reject(&self) -> bool

Checks if the error is a clean reject. A clean reject means that there must be no state changes on the callee side.

fn is_immediately_retryable(&self) -> bool

Determines if the failed call can be retried immediately within the update method that’s handling the error, as opposed to relying on a background timer or heartbeat.

impl Clone for CandidDecodeFailed

fn clone(&self) -> CandidDecodeFailed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CandidDecodeFailed

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

Formats the value using the given formatter.

impl Display for CandidDecodeFailed

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

impl Error for CandidDecodeFailed

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>
