Erlang Interoperability
Understanding Erlang Interoperability in Elixir
Elixir is designed with seamless interoperability with Erlang at its core. This allows developers to leverage the vast ecosystem of Erlang libraries and tools directly within their Elixir projects. Understanding how to call Erlang modules from Elixir is a fundamental skill for any Elixir developer.
Calling Erlang Modules from Elixir
Erlang modules can be called by prepending them with a colon. This syntax signifies that you are invoking a function from an Erlang module. This mechanism is crucial for accessing Erlang's powerful built-in functions and libraries.
:crypto.hash(:sha, "Elixir is the beez knees")
|> :crypto.bytes_to_integer
|> Integer.to_string(16) # "62A3326DEDE3EE38C9C85ED6EC87FD888A130D24"
Benefits of Erlang Integration
By integrating with Erlang, Elixir developers gain access to battle-tested libraries for concurrency, distribution, fault tolerance, and more. This synergy enhances the robustness and scalability of Elixir applications. For instance, the :crypto module provides cryptographic functions that can be used directly.
