Service information

Services expose information about input, internal, and output attributes externally. Useful for complex service processing or testing.

Example service with attributes:

class BuildFullName < ApplicationService::Base
  input :first_name, type: String
  input :middle_name, type: String, required: false
  input :last_name, type: String

  internal :prepared_full_name, type: String

  output :full_name, type: String

  # ...
end

Access attribute information:

BuildFullName.info

# => #<Servactory::Info::Result:0x00000001118c7078 @inputs=[:first_name, :middle_name, :last_name], @internals=[:prepared_full_name], @outputs=[:full_name]>

BuildFullName.info.inputs

# => [:first_name, :middle_name, :last_name]

BuildFullName.info.internals

# => [:prepared_full_name]

BuildFullName.info.outputs

# => [:full_name]
