Enum DataError 

#[non_exhaustive]
pub enum DataError {
    Index(IndexError),
    SubscriptionsEmpty,
    UnsupportedSubKind(SubKind),
    InitialSnapshotMissing(SubscriptionId),
    InitialSnapshotInvalid(String),

    Unsupported {

    },
    InvalidSequence {

All errors generated in rustrade-data.

Non-exhaustive

Variants are added as integrations land, and two of the existing ones (Databento, Lse — not linked: each is behind its own feature, and this block is not) appear only under that feature, so the variant set a downstream match sees already depends on the feature selection it built with. A wildcard arm is required either way; #[non_exhaustive] makes that a compile-time contract rather than something a consumer discovers when a feature flag or a release moves. Matches within this crate stay exhaustively checked.

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.

Index(IndexError)

SubscriptionsEmpty

UnsupportedSubKind(SubKind)

InitialSnapshotMissing(SubscriptionId)

InitialSnapshotInvalid(String)

Socket(String)

Unsupported

Fields

exchange: ExchangeId

sub_kind: SubKind

SubscriberRequired

A dynamic subscription names a venue whose subscriber must be built by the caller — usually because it carries credentials — and none was supplied. See DynamicSubscribers.

Fields

exchange: ExchangeId

FeatureDisabled

The venue serves the subscription, but this build was compiled without the cargo feature that carries its integration.

Fields

exchange: ExchangeId

feature: String

UnsupportedInterval

Fields

exchange: ExchangeId

interval: CandleInterval

InvalidSequence

Fields

prev_last_update_id: u64

first_update_id: u64
