Enum SubscriptionKind

    TransactionReceipts,
}
Available on crate features rpc and serde only.
Expand description

Subscription kind.

Variants§

§

NewHeads

New block headers subscription.

Fires a notification each time a new header is appended to the chain, including chain reorganizations. In case of a chain reorganization the subscription will emit all new headers for the new chain. Therefore the subscription can emit multiple headers on the same height.

§

Logs

Logs subscription.

Returns logs that are included in new imported blocks and match the given filter criteria. In case of a chain reorganization previous sent logs that are on the old chain will be resent with the removed property set to true. Logs from transactions that ended up in the new chain are emitted. Therefore, a subscription can emit logs for the same transaction multiple times.

§

NewPendingTransactions

New Pending Transactions subscription.

Returns the hash or full tx for all transactions that are added to the pending state and are signed with a key that is available in the node. When a transaction that was previously part of the canonical chain isn’t part of the new canonical chain after a reorganization its again emitted.

§

Syncing

Node syncing status subscription.

Indicates when the node starts or stops synchronizing. The result can either be a boolean indicating that the synchronization has started (true), finished (false) or an object with various progress indicators.

§

TransactionReceipts

New transaction receipts subscription.

Returns transaction receipts that are included in new imported blocks and match the given filter criteria. In case of a chain reorganization the subscription will emit transaction receipts for the new chain if they match the filter criteria. Therefore, the subscription can emit same transaction receipts multiple times.
