## Input Examples
* `:bs` => `Set<StringIO>`
* `:ns` => `Set<BigDecimal>`
* `:ss` => `Set<String>`
* `:bool` => `true` or `false`
* `:null` => `nil`
* `:b` => `StringIO`
* `:n` => `BigDecimal`
* `:s` => `String`
* `:l` => `Array`
* `:m` => `Hash`
Members are unmarshalled into the following objects:
* `nil` => `:null`
* `true` or `false` => `:bool`
* `Set<Object>` => `:ss` or `:ns` or `:bs`
* `StringIO` or `IO` => `:b`
* `Numeric` => `:n`
* `String` or `Symbol` or `#to_str` => `:s`
* `Array` => `:l`
* `Hash` or `#to_h` => `:m`
Members are marshalled using the following objects:
ddb = Aws::DynamoDB::Client.new(simple_attributes: false)
`simple_attributes: false` to the client constructor:
objects. You can disable this plugin by passing
