The verifiable instance is required.
Set the verifiable rule to be optional.
const r = eq({

b: string // .required by default
})
r.ok({ b: 'abc' }) === true
r.ok({ a: 'abc' }) === false

) === true
Gets the rule string
oneOf(['123', string]).getRuleString() === "['123', string]"
Gets the type name
oneOf(['123', string]).getTypeName() === "oneOf"
Merge rules
set rule
eq({ a: 'a' }).set('a', 'bbb').ok({ a: 'bbb' }) === true
eq({ a: 'a' }).set(null, 'bbb').ok('bbb') === true
Gets the verifiable instance string
oneOf(['123', string]).getRuleString() === "oneOf(['123', string])"
be('2').toUnlawfulString('2') === ''
be('2').toUnlawfulString(2) === "expected: '2', actual: 2."
