module Lumberjack
# This class can be used as a return value from an AttributeFormatter to indicate that the
# value should be remapped to a new attribute name.
#
# @example
# # Transform duration_millis and duration_micros to seconds and move to
# # the duration attribute.
# logger.formatter.format_attribute_name("duration_ms") do |value|
# Lumberjack::RemapAttribute.new("duration" => value.to_f / 1000)
# end
# logger.formatter.format_attribute_name("duration_micros") do |value|
# Lumberjack::RemapAttribute.new("duration" => value.to_f / 1_000_000)
# end
class RemapAttribute
attr_reader :attributes
# @param remapped_attributes [Hash] The remapped attribute with the new names.
