TransactionSubscription
Namespace: IotaSdk
A live subscription.
Call next in a loop to receive updates; it only returns None once
cancel has been called, since the subscription itself never ends.
public class TransactionSubscription : ITransactionSubscription, System.IDisposable

Parameters
pointer UInt64
Methods
Destroy()
public void Destroy()
Dispose()
public void Dispose()
Cancel()
Cancel the subscription, dropping the connection and unblocking
a pending next.
Idempotent, and safe to call while next is pending — the
pending call drops the connection on its way out.
Named cancel rather than close because a close method
collides with the disposal method uniffi generates for objects
in some languages.
public void Cancel()
IsCanceled()
Whether the subscription has been canceled.
public bool IsCanceled()
Returns
Next()
Wait for the next update.
Returns None once the subscription has been canceled.
Concurrent calls are serialized; there is no ordering guarantee
between them.
Raises for errors the subscription cannot recover from by
itself, such as a rejected filter. The subscription stays
usable afterwards, so a caller that considers the error
transient can keep calling next.
