Struct aws_sdk_cloudsearch::model::Expression

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

A named expression that can be evaluated at search time. Can be used to sort the search results, define other expressions, or return computed information in the search results.

Implementations

impl Expression

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

Names must begin with a letter and can contain the following characters: a-z (lowercase), 0-9, and _ (underscore).

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

The expression to evaluate for sorting while processing a search request. The Expression syntax is based on JavaScript expressions. For more information, see Configuring Expressions in the Amazon CloudSearch Developer Guide.

impl Expression

pub fn builder() -> Builder

Creates a new builder-style object to manufacture Expression.

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl PartialEq<Expression> for Expression

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