Overview

Raised by ::Encoding and ::String methods when the string being transcoded contains a byte invalid for the either the source or target encoding.

Class Attribute Summary

::Exception - Inherited

.to_tty?

Returns true if exception messages will be sent to a terminal device.

Class Method Summary

::Exception - Inherited

.exception

Returns an exception object of the same class as self; useful for creating a similar exception, but with a different message.
.new

Returns a new exception object.

::Exception - Inherited

#==

Returns whether other is the same class as self and its #message and #backtrace are equal to those of self.
#backtrace

Returns the backtrace (the list of code locations that led to the exception), as an array of strings.
#backtrace_locations

Returns the backtrace (the list of code locations that led to the exception), as an array of ::Thread::Backtrace::Location instances.
#cause

Returns the previous value of global variable $!, which may be nil (see Global Variables):
#detailed_message

Returns the message string with enhancements:
#exception

Returns an exception object of the same class as self; useful for creating a similar exception, but with a different message.
#full_message

Returns an enhanced message string:
#inspect

Returns a string representation of self:
#message

Returns #to_s.
#set_backtrace

Sets the backtrace value for self; returns the given value.
#to_s

Returns a string representation of self:
