Rerouted (cache, verified). The original is gone. This copy comes from a Lamdera package cache made before it went. The Lamdera package server serves a copy recovered from a Lamdera package cache from 2021-02-13.
What we checked: Rebuilt from the unpacked sources in a Lamdera package cache (5 copies agree), which Elm only writes after the published SHA-1 checked out; elm.json is byte-identical to package.elm-lang.org's; the exposed modules match docs.json; the zip is our own, so its SHA-1 is not the published one.
The Lamdera compiler uses this copy and prints a one-line notice saying so. elm itself fails to download this version.

This module exposes a type representing all of the messages that can be passed from a host application to the host library. It's a fairly direct mapping to the host-facing API.
Decoder for parsing incoming messages from the application to the relevant types. Bad input from apps will produce nice console errors that describe the exact failure.
This custom type is just a set of variants for each valid message the app can send to the host library. See the individual type descriptions for more details on message structures.
