@section State transitions
|
|
|
|
Queued transactions are controlled using a combination of state bits, enumerated to human-readable labels.
|
|
|
|
Some of these bits may only be set if certain bits have previously been set.
|
|
|
|
Certain combinations of bits constitute @emph{semantic} states, intended for human consumption.
|
|
|
|
|
|
@subsection State bits
|
|
|
|
@table @code
|
|
@item QUEUED
|
|
Transaction is ready to send to network.
|
|
@item RESERVED
|
|
Transaction is assigned to a process which will send it to the network.
|
|
@item IN_NETWORK
|
|
The transaction has been sent to the network.
|
|
@item DEFERRED
|
|
A transaction send could not be completed, and should be retried later.
|
|
@item GAS_ISSUES
|
|
The transaction sender does not have sufficient network token balance to send the transaction.
|
|
@item LOCAL_ERROR
|
|
The transaction request could not be sent, e.g. because the node was unavailable.
|
|
@item NODE_ERROR
|
|
The network gateway node rejected the transaction. (will always be a FINAL state).
|
|
@item NETWORK_ERROR
|
|
The network rejected the state change requested by the transaction (will always be a FINAL state).
|
|
@item UNKNOWN_ERROR
|
|
Any other error (will always be a FINAL state).
|
|
@item FINAL
|
|
The transaction request will not be processed further.
|
|
@item OBSOLETE
|
|
The transaction request has been superseded by a different transaction, e.g. an identical replacement transaction with a higher fee.
|
|
@item MANUAL
|
|
The state of the transaction request has been manipulated manually.

When the @strong{FINAL} bit is set, no further state changes may be made.
