Struct Transform 

#[non_exhaustive]
pub struct Transform {
    pub expression: String,
    pub variables: Vec<ExpressionVariable>,
    pub processing_config: Option<TransformProcessingConfig>,
}

Contains an asset transform property. A transform is a one-to-one mapping of a property's data points from one form to another. For example, you can use a transform to convert a Celsius data stream to Fahrenheit by applying the transformation expression to each data point of the Celsius stream. A transform can only have a data type of DOUBLE and consume properties with data types of INTEGER or DOUBLE.

For more information, see Transforms in the IoT SiteWise User Guide.

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: String

The mathematical expression that defines the transformation function. You can specify up to 10 variables per expression. You can specify up to 10 functions per expression.

For more information, see Quotas in the IoT SiteWise User Guide.

variables: Vec<ExpressionVariable>

The list of variables used in the expression.

processing_config: Option<TransformProcessingConfig>

The processing configuration for the given transform property. You can configure transforms to be kept at the edge or forwarded to the Amazon Web Services Cloud. You can also configure transforms to be computed at the edge or in the cloud.

Implementations

impl Transform

pub fn expression(&self) -> &str

The mathematical expression that defines the transformation function. You can specify up to 10 variables per expression. You can specify up to 10 functions per expression.

For more information, see Quotas in the IoT SiteWise User Guide.

pub fn variables(&self) -> &[ExpressionVariable]

The list of variables used in the expression.

pub fn processing_config(&self) -> Option<&TransformProcessingConfig>

The processing configuration for the given transform property. You can configure transforms to be kept at the edge or forwarded to the Amazon Web Services Cloud. You can also configure transforms to be computed at the edge or in the cloud.

impl Transform

pub fn builder() -> TransformBuilder

Creates a new builder-style object to manufacture Transform.

Trait Implementations

impl Clone for Transform

fn clone(&self) -> Transform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transform

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

Formats the value using the given formatter.

impl PartialEq for Transform

fn eq(&self, other: &Transform) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
