Procedural macros for the FastEdge Rust SDK.

This crate provides the #[fastedge::http] attribute macro for creating WebAssembly HTTP handlers for edge computing applications.

Overview

The #[fastedge::http] macro transforms a regular Rust function into a WebAssembly component that can process HTTP requests in the FastEdge runtime.

Usage

This crate is typically used through the main fastedge crate and is not used directly.

use anyhow::Result;
use fastedge::body::Body;
use fastedge::http::{Request, Response, StatusCode};

#[fastedge::http]
fn main(_req: Request<Body>) -> Result<Response<Body>> {
    Response::builder()
        .status(StatusCode::OK)
        .body(Body::from("Hello, FastEdge!"))
        .map_err(Into::into)
}

Requirements

The handler function must:

  • Accept a single parameter of type Request<Body>
  • Return Result<Response<Body>> (typically using anyhow::Result)
  • Be a free function (not a method)

See the fastedge crate documentation for complete usage information and examples.
