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.

tracingtracing

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.

spawn_graceful_shutdown_handlerUnix and graceful-shutdown

Spawns a task that will be execute a provided async closure when the process receives unix graceful shutdown signals. If the closure takes longer than 500ms to execute, an unhandled SIGKILL signal might be received.

Type Aliases

Error

Error type that lambdas may result in
