Struct DynamoDBAction 

pub struct DynamoDBAction {
    pub hash_key_field: String,
    pub hash_key_type: Option<String>,
    pub hash_key_value: String,
    pub operation: Option<String>,
    pub payload_field: Option<String>,
    pub range_key_field: Option<String>,
    pub range_key_type: Option<String>,
    pub range_key_value: Option<String>,
    pub role_arn: String,
    pub table_name: String,
}

Describes an action to write to a DynamoDB table.

The tableName, hashKeyField, and rangeKeyField values must match the values used when you created the table.

The hashKeyValue and rangeKeyvalue fields use a substitution template syntax. These templates provide data at runtime. The syntax is as follows: ${sql-expression}.

You can specify any valid expression in a WHERE or SELECT clause, including JSON properties, comparisons, calculations, and functions. For example, the following field uses the third level of the topic:

"hashKeyValue": "${topic(3)}"

The following field uses the timestamp:

"rangeKeyValue": "${timestamp()}"

Fields

hash_key_field: String

The hash key name.

hash_key_type: Option<String>

The hash key type. Valid values are "STRING" or "NUMBER"

hash_key_value: String

The hash key value.

operation: Option<String>

The type of operation to be performed. This follows the substitution template, so it can be ${operation}, but the substitution must result in one of the following: INSERT, UPDATE, or DELETE.

payload_field: Option<String>

The action payload. This name can be customized.

range_key_field: Option<String>

The range key name.

range_key_type: Option<String>

The range key type. Valid values are "STRING" or "NUMBER"

range_key_value: Option<String>

The range key value.

role_arn: String

The ARN of the IAM role that grants access to the DynamoDB table.

table_name: String

The name of the DynamoDB table.

Trait Implementations

impl Clone for DynamoDBAction

fn clone(&self) -> DynamoDBAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamoDBAction

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

Formats the value using the given formatter.

impl Default for DynamoDBAction

fn default() -> DynamoDBAction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DynamoDBAction

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DynamoDBAction

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
