Struct ExtensionRuntime 

Source
pub struct ExtensionRuntime { /* private fields */ }
Expand description

Extension runtime that orchestrates all components.

Implementations§

Source§

impl ExtensionRuntime

Source

pub fn new(config: Config) -> Self

Creates a new extension runtime with the given configuration.

Source

pub fn with_defaults() -> Self

Creates a runtime with default configuration.

Source

pub fn with_resource(self, resource: SdkResource) -> Self

Sets a custom resource for this runtime.

Source

pub fn cancellation_token(&self) -> CancellationToken

Returns a handle to the cancellation token.

Source

pub async fn run(self) -> Result<(), RuntimeError>

Runs the extension runtime.

This method uses the official lambda_extension crate with Tower services for proper lifecycle management. It:

  1. Registers with the Extensions API
  2. Subscribes to the Telemetry API for platform events
  3. Starts the OTLP receiver for function telemetry
  4. Runs the event loop until shutdown
§Errors

Returns an error if any component fails to start or if the extension cannot register with Lambda.
