Crate momento_functions 

Code generation helpers for Momento Functions

This crate generates Momento Functions webassembly bindings.

Functions use wasm32-wasip2 as the target architecture. They use the WIT Component Model to describe the ABI.

You are likely to be interested in the sibling crates:

• momento-functions-host: Interfaces and tools for calling host interfaces.
• momento-functions-log: Standard log adapter.

Macros

post

Create a handler that accepts a post payload and returns a response.

spawn

Create a handler for a momento::host::spawn::spawn_function.

Structs

WebError

A WebError represents an error result produced by a function execution. Functionally, it is also just an HTTP response - however, this allows for writing functions with a return signature of WebResult if you are okay with all errors being converted to 500s and returned in the body.

WebResponse

This represents a response from a web function. When constructed, it’s a 200 response with no headers or body. You can set the status, headers, and body via WebResponse::with_status, WebResponse::with_headers, and WebResponse::with_body respectfully.

Traits

IntoWebResponse

Values returned by a function implemented with the crate::post! macro must implement this trait.

Type Aliases

WebResult

A Result type for implementing functions. Allows you to use ? within your function body to return a 500 with the error details.
