NnsGovernanceError

Portable failure returned while collecting or assembling a Governance report.

Variants

UnsupportedNetwork

The requested network is not the supported mainnet identity.

Fields

network: String

Rejected network identity.

InvalidSourceSelection

The selected transport cannot be executed by the source adapter.

Fields

reason: String

Validation failure.

SourceEvidenceMismatch

Returned provenance did not match the requested transport.

Fields

reason: String

Evidence mismatch.

AgentBuild

Native IC agent setup failed.

Fields

endpoint: String

Endpoint used to build the agent.

reason: String

Agent construction failure.

AgentCall

A native IC agent query failed.

Fields

method: &'static str

Governance method being queried.

reason: String

Query failure.

InterCanisterCall

A replicated inter-canister call could not be submitted.

Fields

method: &'static str

Governance method being called.

reason: String

Cycle-balance or call-perform failure.

InterCanisterCallRejected

A replicated inter-canister call returned an IC reject.

Fields

method: &'static str

Governance method being called.

reject_code: u32

Raw IC reject code.

message: String

Reject message returned by the IC.

CandidEncode

A Candid request could not be encoded.

Fields

message: &'static str

Candid request type.

reason: String

Encoding failure.

CandidDecode

A Candid response could not be decoded.

Fields

message: &'static str

actual_bytes: usize

Actual response size.

maximum_bytes: usize

Maximum accepted response size.

Governance

Governance returned its typed application-level error.

Fields

error_type: i32

Trait Implementations

impl Debug for NnsGovernanceError

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

Formats the value using the given formatter.

impl Display for NnsGovernanceError

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

Formats the value using the given formatter.

impl Error for NnsGovernanceError

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.
