Protocol consolidation is useful in production when no dynamic code loading will happen, effectively optimizing protocol dispatches by not accounting for code loading.
This task consolidates all protocols in the code path and outputs the new binary files to the given directory. Defaults to "_build/MIX_ENV/lib/YOUR_APP/consolidated" for regular apps and "_build/MIX_ENV/consolidated" in umbrella projects.
In case you are manually compiling protocols or building releases, you need to take the generated protocols into account. This can be done with:
$ elixir -pa _build/MIX_ENV/lib/YOUR_APP/consolidated -S mix run
Or in umbrellas:
$ elixir -pa _build/MIX_ENV/consolidated -S mix run
You can verify a protocol is consolidated by checking its attributes:
iex> Protocol.consolidated?(Enumerable) true
