Represents the data for an attribute.

Each attribute value is described as a name-value pair. The name is the data type, and the value is the data itself.

For more information, see Data Types in the Amazon DynamoDB Developer Guide.

Fields

b: Option<Bytes>

An attribute of type Binary. For example:

"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"

bool: Option<bool>

An attribute of type Boolean. For example:

"BOOL": true

bs: Option<Vec<Bytes>>

An attribute of type Binary Set. For example:

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

l: Option<Vec<AttributeValue>>

An attribute of type List. For example:

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

m: Option<HashMap<String, AttributeValue>>

An attribute of type Map. For example:

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

n: Option<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.

ns: Option<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.

null: Option<bool>

An attribute of type Null. For example:

"NULL": true

s: Option<String>

An attribute of type String. For example:

"S": "Hello"

ss: Option<Vec<String>>

An attribute of type String Set. For example:

"SS": ["Giraffe", "Hippo" ,"Zebra"]
