Struct aws_sdk_cloudsearch::model::Expression

#[non_exhaustive]
pub struct Expression {
    pub expression_name: Option<String>,
    pub expression_value: Option<String>,
}

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.

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.

expression_name: Option<String>

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

expression_value: Option<String>

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.

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
