Struct aws_sdk_dynamodb::types::Get

#[non_exhaustive]
pub struct Get {
    pub key: Option<HashMap<String, AttributeValue>>,
    pub table_name: Option<String>,
    pub projection_expression: Option<String>,
    pub expression_attribute_names: Option<HashMap<String, String>>,
}

Specifies an item and related attribute values to retrieve in a TransactGetItem object.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

key: Option<HashMap<String, AttributeValue>>

A map of attribute names to AttributeValue objects that specifies the primary key of the item to retrieve.

table_name: Option<String>

The name of the table from which to retrieve the specified item.

projection_expression: Option<String>

A string that identifies one or more attributes of the specified item to retrieve from the table. The attributes in the expression must be separated by commas. If no attribute names are specified, then all attributes of the specified item are returned. If any of the requested attributes are not found, they do not appear in the result.

expression_attribute_names: Option<HashMap<String, String>>

One or more substitution tokens for attribute names in the ProjectionExpression parameter.

Implementations

impl Get

pub fn key(&self) -> Option<&HashMap<String, AttributeValue>>

A map of attribute names to AttributeValue objects that specifies the primary key of the item to retrieve.

pub fn table_name(&self) -> Option<&str>

The name of the table from which to retrieve the specified item.

pub fn projection_expression(&self) -> Option<&str>

A string that identifies one or more attributes of the specified item to retrieve from the table. The attributes in the expression must be separated by commas. If no attribute names are specified, then all attributes of the specified item are returned. If any of the requested attributes are not found, they do not appear in the result.

pub fn expression_attribute_names(&self) -> Option<&HashMap<String, String>>

One or more substitution tokens for attribute names in the ProjectionExpression parameter.

impl Get

pub fn builder() -> GetBuilder

Creates a new builder-style object to manufacture Get.

Trait Implementations

impl Clone for Get

fn clone(&self) -> Get

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Get

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

Formats the value using the given formatter.

impl PartialEq<Get> for Get

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

This method tests for self and other values to be equal, and is used by ==.

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

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