Crate lambda_extension

This module includes utilities to create Lambda Runtime Extensions.

Create a type that conforms to the Extension trait. This type can then be passed to the the lambda_extension::run function, which launches and runs the Lambda runtime extension.

Re-exports

• pub use tower;

Modules

• requests
  Include several request builders to interact with the Extension API.
• tracing
  Utilities to initialize and use tracing and tracing-subscriber in Lambda Functions. This module provides primitives to work with tracing and tracing-subscriber in Lambda functions.

Structs

• Extension
  An Extension that runs event, log and telemetry processors
• ExtensionError
  Simple error that encapsulates human readable descriptions

• SharedService
  A MakeService that produces services by cloning an inner service.
• ShutdownEvent
  Event received when a Lambda function shuts down.
• Span
  Span
• TraceContext
  Tracing Context
• Tracing
  Request tracing information
