class LocalJumpError

Raised when Ruby can't yield as requested.

A typical scenario is attempting to yield when no block is given:

def call_block
  yield 42
end
call_block

raises the exception:

LocalJumpError: no block given (yield)

A more subtle example:

def get_me_a_return
  Proc.new { return 42 }
end
get_me_a_return.call

raises the exception:

LocalJumpError: unexpected return

exit_value → obj Show source

static VALUE
localjump_xvalue(VALUE exc)
{
    return rb_iv_get(exc, "@exit_value");
}

Returns the exit value associated with this LocalJumpError.

reason → symbol Show source

static VALUE
localjump_reason(VALUE exc)
{
    return rb_iv_get(exc, "@reason");
}

The reason this block was terminated: :break, :redo, :retry, :next, :return, or :noreason.
