NnsProposalActivityError

Deterministic validation or accounting failure from local proposal activity projection.

Variants

InvalidCollectionState

The supplied collection state failed its shared continuation invariants.

Fields

reason: String

Deterministic collection invariant failure.

CollectionNotComplete

The collection stopped without observing Governance API exhaustion.

Fields

status: NnsGovernanceCollectionStatus

Current lifecycle of the otherwise valid collection state.

InvalidTimeWindow

The requested half-open proposal time window is empty or reversed.

Fields

from_proposal_timestamp_seconds: u64

Inclusive lower proposal-creation timestamp bound.

until_proposal_timestamp_seconds: u64

Exclusive upper proposal-creation timestamp bound.

ProposalCountMismatch

The supplied rows do not match the collection’s admitted-row accounting.

Fields

expected: u64

Proposal rows accounted for by the collection state.

actual: u64

Proposal rows supplied to the builder.

MissingProposalId

A supplied row has no proposal identifier.

ZeroProposalId

A supplied row uses the reserved zero proposal identifier.

DuplicateProposalId

A supplied proposal identifier occurs more than once.

Fields

proposal_id: u64

Repeated proposal identifier.

ZeroProposalTimestamp

A supplied proposal has no meaningful creation timestamp.

Fields

proposal_id: u64

Proposal identifier attached to the zero timestamp.

AccountingOverflow

A row-count conversion or aggregate increment exceeded u64.

Fields

field: &'static str

Count or conversion that exceeded its representation.

Trait Implementations

impl Debug for NnsProposalActivityError

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

Formats the value using the given formatter.

impl Display for NnsProposalActivityError

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

Formats the value using the given formatter.

impl Error for NnsProposalActivityError

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.
