Base¶

Events¶

UnexpectedError¶

An unexpected error happened that should be investigated.

Attributes¶

Name	Type	Composition
None	`Option<DispatchError>`	`(None, {'Other': None, 'CannotLookup': None, 'BadOrigin': None, 'Module': {'index': 'u8', 'error': '[u8; 4]'}, 'ConsumerRemaining': None, 'NoProviders': None, 'TooManyConsumers': None, 'Token': ('NoFunds', 'WouldDie', 'BelowMinimum', 'CannotCreate', 'UnknownAsset', 'Frozen', 'Unsupported'), 'Arithmetic': ('Underflow', 'Overflow', 'DivisionByZero'), 'Transactional': ('LimitReached', 'NoLayer'), 'Exhausted': None, 'Corruption': None, 'Unavailable': None})`

Constants¶

MaxLen¶

Value¶

Python¶

constant = substrate.get_constant('Base', 'MaxLen')

Errors¶

CounterOverflow¶

The sequence counter for something overflowed.

When this happens depends on e.g., the capacity of the identifier type. For example, we might have pub struct PipId(u32);, with u32::MAX capacity. In practice, these errors will never happen but no code path should result in a panic, so these corner cases need to be covered with an error variant.

TooLong¶

Exceeded a generic length limit. The limit could be for any sort of lists of things, including a string.
