defmodule LogiStd.Sink.Console do
  @moduledoc """
  A sink which prints log messages to the console.

  Behaviours: `Logi.SinkWriter`.

  ## Note

  The sink has no overload protections,
  so it is recommended to use it together with (for example) `LogiStd.Sink.FlowLimiter`
  in a production environment.

  ## Examples

  ```
  iex> Logi.Channel.install_sink(LogiStd.Sink.Console.new(:foo), :info)

  iex> require Logi
  iex> Logi.info "hello world"
  #OUTPUT# 2016-12-05 23:11:53.711 [info] nonode@nohost <0.159.0> nil:nil:5 [] hello world
  ```

  Uses other layout:

  ```
  iex> Logi.Channel.install_sink(LogiStd.Sink.Console.new(:foo, LogiStd.Layout.IoLibFormat.new), :info).
  iex> Logi.info "hello world"
  #OUTPUT# hello world
  ```
