The Error class is a metadata with no behavior. It's used to describe an error that happened during Framework work or during the validation.
To create a custom error you basically just need to fill the required class fields:
from frictionless import errors
class DuplicateRowError(errors.RowError):
code = "duplicate-row"
name = "Duplicate Row"
tags = ["#table", "#row", "#duplicate"]
template = "Row at position {rowPosition} is duplicated: {note}"
description = "The row is duplicated."
The Stats represent various describe/validate stats:
from frictionless import describe
resource = describe('table.csv', stats=True)
print(resource.stats)
{'md5': '6c2c61dd9b0e9c6876139a449ed87933',
'sha256': 'a1fd6c5ff3494f697874deeb07f69f8667e903dd94a7bc062dd57550cea26da8',
'bytes': 30,
'fields': 2,
'rows': 2}Error representation. It is a baseclass from which other subclasses of errors are inherited or derived from.
