=head2 on_ctime_changed $new_ctime, $old_ctime

Invoked when each of the individual C<stat()> fields have changed. All the
C<stat()> fields are supported apart from C<blocks> and C<blksize>. Each is
passed the new and old values of the field.

=head2 on_devino_changed $new_stat, $old_stat

Invoked when either of the C<dev> or C<ino> fields have changed. It is passed
two L<File::stat> instances containing the complete old and new C<stat()>
fields. This can be used to observe when a named file is renamed; it will not
be observed to happen on opened filehandles.

=head2 on_stat_changed $new_stat, $old_stat

Invoked when any of the C<stat()> fields have changed. It is passed two
L<File::stat> instances containing the old and new C<stat()> fields.

=head2 handle => IO

The opened filehandle to watch for C<stat()> changes if C<filename> is not
supplied.

=head2 filename => STRING

Optional. If supplied, watches the named file rather than the filehandle given
in C<handle>. The file will be opened for reading and then watched for
renames. If the file is renamed, the new filename is opened and tracked
similarly after closing the previous file.

=head2 interval => NUM

Optional. The interval in seconds to poll the filehandle using C<stat(2)>
looking for size changes. A default of 2 seconds will be applied if not
defined.

=head1 PARAMETERS

The following named parameters may be passed to C<new> or C<configure>, in
addition to the parameters relating to reading supported by
L<IO::Async::Stream>.

=head2 filename => STRING

Optional. If supplied, watches the named file rather than the filehandle given
in C<read_handle>. The file will be opened by the constructor, and then
watched for renames. If the file is renamed, the new filename is opened and
tracked similarly after closing the previous file.

=head2 interval => NUM

Optional. The interval in seconds to poll the filehandle using C<stat(2)>
looking for size changes. A default of 2 seconds will be applied if not
defined.
