Expand description

The value for an attribute that comes from DynamoDb.

Variants§

§

N(String)

An attribute of type Number. For example:

"N": "123.45"

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

§

S(String)

An attribute of type String. For example:

"S": "Hello"
§

Bool(bool)

An attribute of type Boolean. For example:

"BOOL": true
§

B(Vec<u8>)

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

Type: Base64-encoded binary data object

§

Null(bool)

An attribute of type Null. For example:

"NULL": true
§

M(HashMap<String, AttributeValue>)

An attribute of type Map. For example:

"M": {"Name": {"S": "Joe"}, "Age": {"N": "35"}}

Key Length Constraints: Maximum length of 65535.

§

L(Vec<AttributeValue>)

An attribute of type List. For example:

"L": [ {"S": "Cookies"} , {"S": "Coffee"}, {"N": "3.14159"}]
§

Ss(Vec<String>)

An attribute of type String Set. For example:

"SS": ["Giraffe", "Hippo" ,"Zebra"]
§

Ns(Vec<String>)

An attribute of type Number Set. For example:

"NS": ["42.2", "-19", "7.5", "3.14"]

Numbers are sent across the network to DynamoDB as strings, to maximize compatibility across languages and libraries. However, DynamoDB treats them as number type attributes for mathematical operations.

§

Bs(Vec<Vec<u8>>)

An attribute of type Binary Set. For example:

"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]

Type: Array of Base64-encoded binary data objects
