class Unpicklable(node: object, reason: str)

Bases: Violation

node: object

reason: str

template: AbstractClassVar[str] = '{node!r} does not pickle ({reason}): a lambda or a local function has no name to be found by; bind it at module level'

e.g. ‘output {place!r} is owned by both {other!r} and {node!r}’

Type:

Wording

class DefinedInMain(node: object)

Bases: Violation

node: object

template: AbstractClassVar[str] = '{node!r} holds something defined in `__main__`, which loads back only in the process that wrote it; move it into a module'

e.g. ‘output {place!r} is owned by both {other!r} and {node!r}’
