NAME

       Lucy::Object::Err - Exception.

SYNOPSIS

           use Scalar::Util qw( blessed );
           my $bg_merger;
           while (1) {
               $bg_merger = eval {
                   Lucy::Index::BackgroundMerger->new( index => $index );
               };
               last if $bg_merger;
               if ( blessed($@) and $@->isa("Lucy::Store::LockErr") ) {
                   warn "Retrying...\n";
               }
               else {
                   # Re-throw.
                   die "Failed to open BackgroundMerger: $@";
               }
           }

DESCRIPTION

       Most of the time when Lucy encounters an error, it tries to raise a Lucy::Object::Err
       exception with an error message and context information.

       At present, it is only safe to catch exceptions which are specifically documented as
       catchable; most times when an Err is raised, Lucy leaks memory.

       The Err module also provides access to a per-thread Err shared variable via set_error()
       and get_error().  It may be used to store an Err object temporarily, so that calling code
       may choose how to handle a particular error condition.

INHERITANCE

       Lucy::Object::Err isa Lucy::Object::Obj.
