Hi after the initial success of this template I want to suggest that you add another one to this repo with a suffix of http. The new template would use the new of-watchdog from OpenFaaS which allows for much high throughput by not forking a process for each request.

For an example see the openfaas-incubator org and the Go HTTP template.

Would you like to work on this or should I try to find another Rust developer to cover it? Thanks :)

I decided to try out Rust and OpenFaaS by rendering a needed HTML file. It seemed like I would need an HTTP client for that level of control, so I added hyper.

Results:

Compiling hyper v0.12.11
Compiling handler v0.1.0 (file:///usr/src/openfaas/function)
Compiling main v0.1.0 (file:///usr/src/openfaas/main)
error[E0277]: http::response::Response<hyper::body::body::Body> doesn't implement std::fmt::Display

error: aborting due to previous error

Question:

I understand that the request is handled for us, but don't we need to control the response in order to render HTML pages and return JSON?

Hey,

I found this template when I started playing with functions just the other day, and it's a nice setup so far. However, I can't figure out how to (if there is a way) to change the status code of a response, to indicate to the caller that the input is invalid or that something went wrong?

Cheers!
