[−][src]Struct rusoto_dynamodb::AttributeValue
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<Vec<u8>>
An attribute of type Binary. For example:
"B": "dGhpcyB0ZXh0IGlzIGJhc2U2NC1lbmNvZGVk"
bool: Option<bool>
An attribute of type Boolean. For example:
"BOOL": true
bs: Option<Vec<Vec<u8>>>
An attribute of type Binary Set. For example:
"BS": ["U3Vubnk=", "UmFpbnk=", "U25vd3k="]
l: Option<Vec<AttributeValue>>
An attribute of type List. For example:
"L": ["Cookies", "Coffee", 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"]
