Struct AttributeValue

pub struct AttributeValue {
    pub b: Option<Bytes>,
    pub bool: Option<bool>,
    pub bs: Option<Vec<Bytes>>,
    pub l: Option<Vec<AttributeValue>>,
    pub m: Option<HashMap<String, AttributeValue>>,
    pub n: Option<String>,
    pub ns: Option<Vec<String>>,
    pub null: Option<bool>,
    pub s: Option<String>,
    pub ss: Option<Vec<String>>,
}

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"]

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AttributeValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AttributeValue

fn default() -> AttributeValue

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AttributeValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AttributeValue

fn eq(&self, other: &AttributeValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AttributeValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
