Struct aws_sdk_iotevents::types::AssetPropertyVariant

#[non_exhaustive]
pub struct AssetPropertyVariant {
    pub string_value: Option<String>,
    pub integer_value: Option<String>,
    pub double_value: Option<String>,
    pub boolean_value: Option<String>,
}

A structure that contains an asset property value. For more information, see Variant in the AWS IoT SiteWise API Reference.

You must use expressions for all parameters in AssetPropertyVariant. The expressions accept literals, operators, functions, references, and substitution templates.

Examples

• For literal values, the expressions must contain single quotes. For example, the value for the integerValue parameter can be '100'.

• For references, you must specify either variables or parameters. For example, the value for the booleanValue parameter can be $variable.offline.

• For a substitution template, you must use ${}, and the template must be in single quotes. A substitution template can also contain a combination of literals, operators, functions, references, and substitution templates.

  In the following example, the value for the doubleValue parameter uses a substitution template.

  '${$input.TemperatureInput.sensorData.temperature * 6 / 5 + 32}'

For more information, see Expressions in the AWS IoT Events Developer Guide.

You must specify one of the following value types, depending on the dataType of the specified asset property. For more information, see AssetProperty in the AWS IoT SiteWise API Reference.

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.

string_value: Option<String>

The asset property value is a string. You must use an expression, and the evaluated result should be a string.

integer_value: Option<String>

The asset property value is an integer. You must use an expression, and the evaluated result should be an integer.

double_value: Option<String>

The asset property value is a double. You must use an expression, and the evaluated result should be a double.

boolean_value: Option<String>

The asset property value is a Boolean value that must be 'TRUE' or 'FALSE'. You must use an expression, and the evaluated result should be a Boolean value.

Implementations

impl AssetPropertyVariant

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

The asset property value is a string. You must use an expression, and the evaluated result should be a string.

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

The asset property value is an integer. You must use an expression, and the evaluated result should be an integer.

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

The asset property value is a double. You must use an expression, and the evaluated result should be a double.

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

The asset property value is a Boolean value that must be 'TRUE' or 'FALSE'. You must use an expression, and the evaluated result should be a Boolean value.

impl AssetPropertyVariant

pub fn builder() -> AssetPropertyVariantBuilder

Creates a new builder-style object to manufacture AssetPropertyVariant.

Trait Implementations

impl Clone for AssetPropertyVariant

fn clone(&self) -> AssetPropertyVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssetPropertyVariant

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

Formats the value using the given formatter.

impl PartialEq for AssetPropertyVariant

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