Rescu all errors and then case statement

Misiek Sz

How can I read what type of error occured in rescue clause.
For example, I have the following:

begin
"some code here"


rescue
case
when "error type 1"

when "error type 2"
end

end

I know I could raise errors within code section and then have specif
rescues, but I want to have one rescue and then do different things with
it in the rescue.

Thanks in advance.

You can do something like this:

begin
...
rescue => e
<do whatever you want with e here>
end

basically, the "=> e" bit will store the thrown error in the "e" variable.

that works good. In addition to that is there a way to tell what error
type is it ?
