NAME

6       Sys::Virt::Error - error object for libvirt APIs
7

DESCRIPTION

9       The "Sys::Virt::Error" class provides an encoding of the libvirt
10       errors. Instances of this object can be thrown by pretty much any of
11       the Sys::Virt APIs.
12

METHODS

14       $err->stringify
15           Convert the object into string format suitable for printing on a
16           console to inform a user of the error.
17
18       my $code = $err->level
19           Return the raw error level represented by this error. One of the
20           ERROR LEVEL CONSTANTS
21
22       my $code = $err->code
23           Return the raw error code represented by this error. One of the
24           ERROR CODE CONSTANTS
25
26       my $from = $err->domain
27           Return the error domain raising this error. One of the ERROR DOMAIN
28           CONSTANTS
29
30       my $msg = $err->message
31           Return an informative message describing the error condition.
