Struct InputTransformer

#[non_exhaustive]
pub struct InputTransformer {
    pub input_paths_map: Option<HashMap<String, String>>,
    pub input_template: String,
}

Contains the parameters needed for you to provide custom input to a target based on one or more pieces of data extracted from the event.

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.

input_paths_map: Option<HashMap<String, String>>

Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.

InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 100 key-value pairs. You must use JSON dot notation, not bracket notation.

The keys cannot start with "Amazon Web Services."

input_template: String

Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value>

If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

• The placeholder cannot be used as an object key.

The following example shows the syntax for using InputPathsMap and InputTemplate.

"InputTransformer":

{

"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

"InputTemplate": " is in state "

}

To have the InputTemplate include quote marks within a JSON string, escape each quote marks with a slash, as in the following example:

"InputTransformer":

{

"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

"InputTemplate": " is in state \" \""

}

The InputTemplate can also be valid JSON with varibles in quotes or out, as in the following example:

"InputTransformer":

{

"InputPathsMap": {"instance": "$.detail.instance","status": "$.detail.status"},

"InputTemplate": '{"myInstance": ,"myStatus": " is in state \" \""}'

}

Implementations

impl InputTransformer

pub fn input_paths_map(&self) -> Option<&HashMap<String, String>>

Map of JSON paths to be extracted from the event. You can then insert these in the template in InputTemplate to produce the output you want to be sent to the target.

InputPathsMap is an array key-value pairs, where each value is a valid JSON path. You can have as many as 100 key-value pairs. You must use JSON dot notation, not bracket notation.

The keys cannot start with "Amazon Web Services."

pub fn input_template(&self) -> &str

Input template where you specify placeholders that will be filled with the values of the keys from InputPathsMap to customize the data sent to the target. Enclose each InputPathsMaps value in brackets: <value>

If InputTemplate is a JSON object (surrounded by curly braces), the following restrictions apply:

impl InputTransformer

pub fn builder() -> InputTransformerBuilder

Creates a new builder-style object to manufacture InputTransformer.

Trait Implementations

impl Clone for InputTransformer

fn clone(&self) -> InputTransformer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputTransformer

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

Formats the value using the given formatter.

impl PartialEq for InputTransformer

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

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

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

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