Crate lambda_runtime

The mechanism available for defining a Lambda function is as follows:

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

Re-exports

• pub use diagnostic::Diagnostic;
• pub use tower;

Modules

• diagnostic
  Diagnostic utilities to convert Rust types into Lambda Error types.
• layers
  Tower middleware to be applied to runtime invocations.
• streaming
  Utilities for Lambda Streaming functions.
• 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

• Config
  Configuration derived from environment variables.
• Context
  The Lambda function execution context. The values in this struct are populated using the Lambda environment variables and the headers returned by the poll request to the Runtime APIs.
• LambdaEvent
  Incoming Lambda request containing the event payload and context.
• LambdaInvocation
  A simple container that provides information about a single invocation of a Lambda function.
• MetadataPrelude
  Metadata prelude for a stream response.
• Runtime
  Lambda runtime executing a handler function on incoming requests.
• StreamResponse
  A streaming response that contains the metadata prelude and the stream of bytes that will be sent to the client.

Enums

• FunctionResponse
  An enum representing the response of a function that can return either a buffered response of type B or a streaming response of type S.

Traits

• IntoFunctionResponse
  a trait that can be implemented for any type that can be converted into a FunctionResponse. This allows us to use the into method to convert a type into a FunctionResponse.
• Service
  An asynchronous function from a Request to a Response.

Functions

• handler_fnDeprecated
  Return a new ServiceFn with a closure that takes an event and context as separate arguments.
• run
  Starts the Lambda Rust runtime and begins polling for events on the Lambda Runtime APIs.
• service_fn
  Returns a new ServiceFn with the given closure.

Type Aliases

• Error
  Error type that lambdas may result in
