18 Span objects store information about a span across an array ofX
19 something. The unit is context-dependent.
20
21 Text is one possibility, in which case offset and length might be
22 measured in Unicode code points. However, the Span could also refer to
23 a span within an array of tokens, for example X in which case the start
24 and offset might be measured in token positions.

27 new
28 my $span = Lucy::Search::Span->new(
29 offset => 75, # required
30 length => 7, # required
31 weight => 1.0, # default 0.0
32 );
33
34 Create a new Span.
35
36 • offset - Integer offset, unit is context-dependent.
37
38 • length - Integer length, unit is context-dependent.
39
40 • weight - A floating point weight.

78
79 • other - Another Obj.
