Enum ScalarAttributeType 

pub enum ScalarAttributeType {
    S,
    N,
    B,
    Unknown(String),
}

Scalar attribute types supported in key schema and attribute definitions.

DynamoDB only allows S, N, and B for key attributes, but the wire protocol may receive other values which must be rejected with a ValidationException rather than a deserialization error.

Variants

S

String type.

N

Number type.

B

Binary type.

Unknown(String)

An unknown/invalid attribute type received from the client.

Implementations

impl ScalarAttributeType

pub fn as_str(&self) -> &str

Returns the DynamoDB wire-format string representation.

pub fn is_valid_key_type(&self) -> bool

Returns true if this is a valid key attribute type (S, N, or B).

Trait Implementations

impl Clone for ScalarAttributeType

fn clone(&self) -> ScalarAttributeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarAttributeType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScalarAttributeType

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ScalarAttributeType

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

Formats the value using the given formatter.

impl Hash for ScalarAttributeType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScalarAttributeType

fn eq(&self, other: &ScalarAttributeType) -> 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 ScalarAttributeType

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
