Storage functions¶

CounterForOverweight¶

Counter for the related counted storage map

Python¶

result = substrate.query(
    'XcmpQueue', 'CounterForOverweight', []
)

Return value¶

'u32'

InboundXcmpMessages¶

Inbound aggregate XCMP messages. It can only be one per ParaId/block.

Python¶

result = substrate.query(
    'XcmpQueue', 'InboundXcmpMessages', ['u32', 'u32']
)

Return value¶

'Bytes'

InboundXcmpStatus¶

Status of the inbound XCMP channels.

Python¶

result = substrate.query(
    'XcmpQueue', 'InboundXcmpStatus', []
)

Return value¶

[
    {
        'message_metadata': [
            (
                'u32',
                (
                    'ConcatenatedVersionedXcm',
                    'ConcatenatedEncodedBlob',
                    'Signals',
                ),
            ),
        ],
        'sender': 'u32',
        'state': ('Ok', 'Suspended'),
    },
]

OutboundXcmpMessages¶

The messages outbound in a given XCMP channel.

Python¶

result = substrate.query(
    'XcmpQueue', 'OutboundXcmpMessages', ['u32', 'u16']
)

Return value¶

'Bytes'

OutboundXcmpStatus¶

The non-empty XCMP channels in order of becoming non-empty, and the index of the first and last outbound message. If the two indices are equal, then it indicates an empty queue and there must be a non-Ok OutboundStatus. We assume queues grow no greater than 65535 items. Queue indices for normal messages begin at one; zero is reserved in case of the need to send a high-priority signal message this block. The bool is true if there is a signal message waiting to be sent.

Python¶

result = substrate.query(
    'XcmpQueue', 'OutboundXcmpStatus', []
)

Return value¶

[
    {
        'first_index': 'u16',
        'last_index': 'u16',
        'recipient': 'u32',
        'signals_exist': 'bool',
        'state': ('Ok', 'Suspended'),
    },
]

Overweight¶

The messages that exceeded max individual message weight budget.

These message stay in this storage map until they are manually dispatched via service_overweight.

Python¶

result = substrate.query(
    'XcmpQueue', 'Overweight', ['u64']
)

Return value¶

('u32', 'u32', 'Bytes')

OverweightCount¶

The number of overweight messages ever recorded in Overweight. Also doubles as the next available free overweight index.

Python¶

result = substrate.query(
    'XcmpQueue', 'OverweightCount', []
)

Return value¶

'u64'

QueueConfig¶

The configuration which controls the dynamics of the outbound queue.

Python¶

result = substrate.query(
    'XcmpQueue', 'QueueConfig', []
)

Return value¶

{
    'drop_threshold': 'u32',
    'resume_threshold': 'u32',
    'suspend_threshold': 'u32',
    'threshold_weight': {'proof_size': 'u64', 'ref_time': 'u64'},
    'weight_restrict_decay': {'proof_size': 'u64', 'ref_time': 'u64'},
    'xcmp_max_individual_weight': {'proof_size': 'u64', 'ref_time': 'u64'},
}

QueueSuspended¶

Whether or not the XCMP queue is suspended from executing incoming XCMs or not.

Python¶

result = substrate.query(
    'XcmpQueue', 'QueueSuspended', []
)

Return value¶

'bool'

SignalMessages¶

Any signal messages waiting to be sent.

Python¶

result = substrate.query(
    'XcmpQueue', 'SignalMessages', ['u32']
)

Return value¶

'Bytes'

Errors¶

BadOverweightIndex¶

Bad overweight index.

BadXcm¶

Bad XCM data.

BadXcmOrigin¶

Bad XCM origin.

FailedToSend¶

Failed to send XCM message.

WeightOverLimit¶

Provided weight is possibly not enough to execute the message.
