Std.Http.Server.Lambda.fromEnvironment

fn

This is a callable function.

What it does

The interface this process was started under, when it was started under one.

Absent everywhere else, which is how a program tells the two apart: serve the

loop when there is an interface to ask, and open a listener when there is

not. The same program then runs under a platform and on a developer's machine

without being built differently for each.
