CoreDescriptors

Assignments which are currently active.

They will be picked from PendingAssignments once we reach the scheduled block number in PendingAssignments.

Python

result = substrate.query(
    'CoretimeAssignmentProvider', 'CoreDescriptors', ['u32']
)

Return value

{
    'current_work': (
        None,
        {
            'assignments': [('scale_info::374', 'scale_info::853')],
            'end_hint': (None, 'u32'),
            'pos': 'u16',
            'step': 'u16',
        },
    ),
    'queue': (None, {'first': 'u32', 'last': 'u32'}),
}

---

CoreSchedules

Scheduled assignment sets.

Assignments as of the given block number. They will go into state once the block number is reached (and replace whatever was in there before).

Python

result = substrate.query(
    'CoretimeAssignmentProvider', 'CoreSchedules', [('u32', 'u32')]
)

Return value

{
    'assignments': [({'Idle': None, 'Pool': None, 'Task': 'u32'}, 'u16')],
    'end_hint': (None, 'u32'),
    'next_schedule': (None, 'u32'),
}
