SYNOPSIS

13         use v5.14;
14         use Attean;
15         my $iter = Attean::CodeIterator->new(
16           generator => sub {
17             state $value = 0;
18             Attean::Literal->new(++$value)
19           },
20           item_type => 'Attean::API::Term',
21         );
22
23         say $iter->next->value; # 1
24         say $iter->next->value; # 2

DESCRIPTION

28       The Attean::CodeIterator class represents a typed iterator.  It
29       conforms to the Attean::API::Iterator role.
30
31       The Attean::CodeIterator constructor requires two named arguments:
32
33       generator
34           A code reference that when called will return either the iterator's
35           next item, or undef upon reaching the end of iteration.
36
37       item_type
38           A Type::Tiny object representing the type of the items that will be
39           returned from the iterator.
40

METHODS

42       "next"
43           Returns the iterator's next item, or undef upon reaching the end of
44           iteration.
