Structured failure from a super::CandidCallExt operation.

Match the variant to inspect its required context and original failure details.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Encode

Arguments could not be Candid-encoded.

Fields

context: Box<CandidCallContext>

Target, caller, method and raw PocketIC operation.

message: String

Original codec failure text.

Decode

Successful response bytes could not be Candid-decoded.

Fields

context: Box<CandidCallContext>

Target, caller, method and raw PocketIC operation.

bytes: usize

Number of reply bytes presented to the decoder.

source: Box<DecodeError>

Original bounded decoder failure.

CanisterReject

PocketIC returned a structured canister rejection.

Fields

context: Box<CandidCallContext>

Target, caller, method and raw PocketIC operation.

response: Box<RejectResponse>

Complete upstream rejection.

Transport

The PocketIC instance became unreachable.

Fields

context: Box<CandidCallContext>

Target, caller, method and raw PocketIC operation.

source: PocketIcOperationError

Original upstream operation failure and transport classification.

Trait Implementations

impl Debug for CandidCallError

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

Formats the value using the given formatter.

impl Display for CandidCallError

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

Formats the value using the given formatter.

impl Error for CandidCallError

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.
