NAME¶
Sys::Virt::Error - error object for libvirt APIs
DESCRIPTION¶
The "Sys::Virt::Error" class provides an encoding of the libvirt errors. Instances of this object can be thrown by pretty much any of the Sys::Virt APIs.
METHODS¶
- $err->stringify
- Convert the object into string format suitable for printing on a console to inform a user of the error.
- my $code = $err->level
- Return the raw error level represented by this error. One of the ERROR LEVEL CONSTANTS
- my $code = $err->code
- Return the raw error code represented by this error. One of the ERROR CODE CONSTANTS
- my $from = $err->domain
- Return the error domain raising this error. One of the ERROR DOMAIN CONSTANTS
- my $msg = $err->message
- Return an informative message describing the error condition.
