Contains parameters for a Lambda function that runs on IoT Greengrass.

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.

event_sources: Option<Vec<LambdaEventSource>>

The list of event sources to which to subscribe to receive work messages. The Lambda function runs when it receives a message from an event source. You can subscribe this function to local publish/subscribe messages and Amazon Web Services IoT Core MQTT messages.

max_queue_size: Option<i32>

The maximum size of the message queue for the Lambda function component. The IoT Greengrass core stores messages in a FIFO (first-in-first-out) queue until it can run the Lambda function to consume each message.

max_instances_count: Option<i32>

The maximum number of instances that a non-pinned Lambda function can run at the same time.

max_idle_time_in_seconds: Option<i32>

The maximum amount of time in seconds that a non-pinned Lambda function can idle before the IoT Greengrass Core software stops its process.

timeout_in_seconds: Option<i32>

The maximum amount of time in seconds that the Lambda function can process a work item.

status_timeout_in_seconds: Option<i32>

The interval in seconds at which a pinned (also known as long-lived) Lambda function component sends status updates to the Lambda manager component.

pinned: Option<bool>

Whether or not the Lambda function is pinned, or long-lived.

• A pinned Lambda function starts when IoT Greengrass starts and keeps running in its own container.

• A non-pinned Lambda function starts only when it receives a work item and exists after it idles for maxIdleTimeInSeconds. If the function has multiple work items, the IoT Greengrass Core software creates multiple instances of the function.

Default: true

input_payload_encoding_type: Option<LambdaInputPayloadEncodingType>

The encoding type that the Lambda function supports.

Default: json

exec_args: Option<Vec<String>>

The list of arguments to pass to the Lambda function when it runs.

environment_variables: Option<HashMap<String, String>>

The map of environment variables that are available to the Lambda function when it runs.

linux_process_params: Option<LambdaLinuxProcessParams>

The parameters for the Linux process that contains the Lambda function.

Implementations

impl LambdaExecutionParameters

pub fn event_sources(&self) -> Option<&[LambdaEventSource]>

pub fn max_queue_size(&self) -> Option<i32>

The maximum size of the message queue for the Lambda function component. The IoT Greengrass core stores messages in a FIFO (first-in-first-out) queue until it can run the Lambda function to consume each message.
