pub struct Builder { /* private fields */ }

A builder for Projection.

Implementations

impl Builder

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.

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.

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

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.

Trait Implementations

impl Clone for Builder

fn clone(&self) -> Builder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.

impl PartialEq<Builder> for Builder

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