github.com/aws/aws-sdk-go-v2/feature/dynamodb/attributevalue (go): Package attributevalue provides marshaling and unmarshaling utilities to convert between Go types and Amazon DynamoDB AttributeValues.  These utilities allow you to marshal slices, maps, structs, and scalar values to and from AttributeValue type. These utilities make it easier to convert between AttributeValue and Go types when working with DynamoDB resources.  This package only converts between Go types and DynamoDB AttributeValue. See the feature/dynamodbstreams/attributevalue package for converting to DynamoDBStreams AttributeValue types.  The FromDynamoStreamsDBMap, FromDynamoStreamsDBList, and FromDynamoDBStreams functions provide the conversion utilities to convert a DynamoDBStreams AttributeValue type to a DynamoDB AttributeValue type. Use these utilities when you need to convert the AttributeValue type between the two APIs.  To marshal a Go type to an AttributeValue you can use the Marshal, MarshalList, and MarshalMap functions. The List and Map functions are specialized versions of the Marshal for serializing slices and maps of Attributevalues.  The following example uses MarshalMap to convert a Go struct, Record to a AttributeValue. The AttributeValue value is then used as input to the PutItem operation call.  To unmarshal an AttributeValue to a Go type you can use the Unmarshal, UnmarshalList, UnmarshalMap, and UnmarshalListOfMaps functions. The List and Map functions are specialized versions of the Unmarshal function for unmarshal slices and maps of Attributevalues.  The following example will unmarshal Items result from the DynamoDB's Scan API operation. The Items returned will be unmarshaled into the slice of the Records struct.  The AttributeValue Marshal and Unmarshal functions support the `dynamodbav` struct tag by default. Additional tags can be enabled with the EncoderOptions and DecoderOptions, TagKey option.  See the Marshal and Unmarshal function for information on how struct tags and fields are marshaled and unmarshaled.
