Struct SessionPlaylistBase 

pub struct SessionPlaylistBase { /* private fields */ }

A base playlist rendered once, so each viewer’s per-session playlist costs one tag line plus a copy of the text — not a deep clone of every segment and a full re-serialisation per viewer per reload (audit r14-SSAI-O1, issue #1125).

The tag line is spliced in immediately before the first #EXT-X-PART: or #EXTINF: line, whichever comes first — i.e. before the first segment’s part/EXTINF group, never between a segment’s parts and its EXTINF (an EXT-X-DATERANGE is not positional within the playlist, RFC 8216bis §4.4.5.1) — or before #EXT-X-ENDLIST / at the end when the base has neither.
