[−][src]Crate lambda_runtime
Lambda runtime makes it easy to run Rust code inside AWS Lambda. To create
Lambda function with this library simply include it as a dependency, make
sure that you declare a function that respects the Handler
type, and call
the start()
function from your main method. The executable in your deployment
package must be called bootstrap
.
#[macro_use] extern crate serde_derive; #[macro_use] extern crate lambda_runtime; use lambda_runtime::error::HandlerError; #[derive(Deserialize, Clone)] struct CustomEvent { first_name: String, last_name: String, } #[derive(Serialize, Clone)] struct CustomOutput { message: String, } fn main() { lambda!(my_handler); } fn my_handler(e: CustomEvent, ctx: lambda_runtime::Context) -> Result<CustomOutput, HandlerError> { if e.first_name == "" { return Err(ctx.new_error("Missing first name!")); } Ok(CustomOutput{ message: format!("Hello, {}!", e.first_name), }) }
Modules
error | The error module defines the error types that can be returned by custom handlers as well as the runtime itself. |
Macros
lambda |
Structs
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.
A new instance of the |
Functions
start | Creates a new runtime and begins polling for events using Lambda's Runtime APIs. |
Type Definitions
Handler | Functions acting as a handler must conform to this type. |
