Method: Logging::Layout#initialize

Defined in:
lib/logging/layout.rb

#initialize(opts = {}) ⇒ Layout

call-seq:

Layout.new( :format_as => :string )

Creates a new layout that will format objecs as strings using the given :format_as style. This can be one of :string, :inspect, or :yaml. These formatting commands map to the following object methods:

  • :string => to_s

  • :inspect => inspect

  • :yaml => to_yaml

If the format is not specified then the global object format is used (see Logging#format_as). If the global object format is not specified then :string is used.
