Struct aws_sdk_dynamodb::types::builders::ProjectionBuilder

#[non_exhaustive]
pub struct ProjectionBuilder { /* private fields */ }

A builder for Projection.

Implementations

impl ProjectionBuilder

pub fn projection_type(self, input: ProjectionType) -> Self

The set of attributes that are projected into the index:

• KEYS_ONLY - Only the index and primary keys are projected into the index.

• INCLUDE - In addition to the attributes described in KEYS_ONLY, the secondary index will include other non-key attributes that you specify.

• ALL - All of the table attributes are projected into the index.

When using the DynamoDB console, ALL is selected by default.

pub fn set_projection_type(self, input: Option<ProjectionType>) -> Self

The set of attributes that are projected into the index:

• KEYS_ONLY - Only the index and primary keys are projected into the index.

• INCLUDE - In addition to the attributes described in KEYS_ONLY, the secondary index will include other non-key attributes that you specify.

• ALL - All of the table attributes are projected into the index.

When using the DynamoDB console, ALL is selected by default.

pub fn get_projection_type(&self) -> &Option<ProjectionType>

The set of attributes that are projected into the index:

• KEYS_ONLY - Only the index and primary keys are projected into the index.

• INCLUDE - In addition to the attributes described in KEYS_ONLY, the secondary index will include other non-key attributes that you specify.

• ALL - All of the table attributes are projected into the index.

When using the DynamoDB console, ALL is selected by default.

pub fn non_key_attributes(self, input: impl Into<String>) -> Self

Appends an item to non_key_attributes.

To override the contents of this collection use set_non_key_attributes.

Represents the non-key attribute names which will be projected into the index.

For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

pub fn set_non_key_attributes(self, input: Option<Vec<String>>) -> Self

Represents the non-key attribute names which will be projected into the index.

For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

pub fn get_non_key_attributes(&self) -> &Option<Vec<String>>

Represents the non-key attribute names which will be projected into the index.

For local secondary indexes, the total count of NonKeyAttributes summed across all of the local secondary indexes, must not exceed 100. If you project the same attribute into two different indexes, this counts as two distinct attributes when determining the total.

pub fn build(self) -> Projection

Consumes the builder and constructs a Projection.

Trait Implementations

impl Clone for ProjectionBuilder

fn clone(&self) -> ProjectionBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionBuilder

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

Formats the value using the given formatter.

impl Default for ProjectionBuilder

fn default() -> ProjectionBuilder

Returns the “default value” for a type.

impl PartialEq for ProjectionBuilder

fn eq(&self, other: &ProjectionBuilder) -> 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.
