Fields

• binaryListValues :: Maybe [Base64]

  Not implemented. Reserved for future use.

• binaryValue :: Maybe Base64

  Binary type attributes can store any binary data, such as compressed data, encrypted data, or images.

• stringListValues :: Maybe [Text]

  Not implemented. Reserved for future use.

• stringValue :: Maybe Text

  Strings are Unicode with UTF-8 binary encoding. For a list of code values, see ASCII Printable Characters.

• dataType :: Text

  Amazon SQS supports the following logical data types: String, Number, and Binary. For the Number data type, you must use StringValue.

  You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide.

$sel:dataType:MessageSystemAttributeValue'

-> MessageSystemAttributeValue

Create a value of MessageSystemAttributeValue with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:binaryListValues:MessageSystemAttributeValue', messageSystemAttributeValue_binaryListValues - Not implemented. Reserved for future use.

$sel:binaryValue:MessageSystemAttributeValue', messageSystemAttributeValue_binaryValue - Binary type attributes can store any binary data, such as compressed data, encrypted data, or images.-- -- Note: This Lens automatically encodes and decodes Base64 data. -- The underlying isomorphism will encode to Base64 representation during -- serialisation, and decode from Base64 representation during deserialisation. -- This Lens accepts and returns only raw unencoded data.

$sel:stringListValues:MessageSystemAttributeValue', messageSystemAttributeValue_stringListValues - Not implemented. Reserved for future use.

$sel:stringValue:MessageSystemAttributeValue', messageSystemAttributeValue_stringValue - Strings are Unicode with UTF-8 binary encoding. For a list of code values, see ASCII Printable Characters.

$sel:dataType:MessageSystemAttributeValue', messageSystemAttributeValue_dataType - Amazon SQS supports the following logical data types: String, Number, and Binary. For the Number data type, you must use StringValue.

You can also append custom labels. For more information, see Amazon SQS Message Attributes in the Amazon SQS Developer Guide.
