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. You can set one, and only one, of the elements.

Each attribute in an item is a name-value pair. An attribute can be single-valued or multi-valued set. For example, a book item can have title and authors attributes. Each book has one title but can have many authors. The multi-valued attribute is a set; duplicate values are not allowed.

m: Option<HashMap<String, AttributeValue>>

A Map data type.

n: Option<String>

A Number data type.

ns: Option<Vec<String>>

A Number Set data type.

null: Option<bool>

A Null data type.

s: Option<String>

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a duplicate 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.
