OeditusCredo.Check.Refactoring.PreferInplaceBinaryMatching (OeditusCredo v0.10.2)

Basics

This check has a base priority of normal and works with any version of Elixir.

Explanation

Checking binary type and non-emptiness in guards can be replaced with direct binary pattern matching in the function parameter list: <<_::utf8, _::binary>> or <<_, _::binary>>.

Bad:

def process(str) when is_binary(str) and str != "" do
  ...
end

Good:

def process(<<_::utf8, _::binary>> = str) do
  ...
end

Check-Specific Parameters

There are no specific parameters for this check.

General Parameters

Like with all checks, general params can be applied.

Parameters can be configured via the .credo.exs config file.
