Rustler recompiles although nothing changed #651
Description
I have an Umbrella App setup where rustler is being used in a ´Core.QrCode` module.
This module has no external compile time dependency except Rustler
defmodule Core.QrCode do
use Rustler,
otp_app: :core,
crate: :qr_code
defmodule QrCodeOptions do
@type t :: %__MODULE__{
content: String.t(),
# ...args
}
defstruct [
:content,
# ...args
]
def new(content, rest \\ %{}) do
struct(__MODULE__, Map.put(rest, :content, content))
end
end
def generate_svg(_arg1), do: :erlang.nif_error(:nif_not_loaded)
endSo when we change almost anything, modules that are not related Core.QrCode, it recompiles causing many other parts of the application to recompile. Since we are heavily using it in another umbrella app, it trigger the recompilation of 80+ files, even if nothing changed.
Is there any way to prevent it from being recompiled when nothing changed?
