Phase 6 — Search + Channel + Playlist + LinkHandler
Pulls in the read-side extractor surfaces Straw needs at app open
(search bar) + on detail screens (channel + playlist).
src/youtube/linkhandler/
* mod.rs — ACCEPTED_HOSTS allowlist (youtube.com /
youtube-nocookie.com / youtu.be / m.youtube.com /
music.youtube.com); 27 Invidious mirror hosts
intentionally dropped (SPEC §6.6).
* stream.rs — extract_video_id() handles /watch?v= / youtu.be/ /
/embed/ / /shorts/ / /v/ / /live/ / attribution_link;
strict 11-char [A-Za-z0-9_-] validation.
* channel.rs — ChannelIdentifier enum (DirectId / Handle / Custom /
LegacyUser). Resolution to UC… id lands in
youtube/channel.rs.
* playlist.rs — extracts ?list=<PLid> from /playlist and /watch URLs.
* search.rs — SearchFilter enum + params() opaque base64 strings +
uses_music_endpoint() routing flag.
src/youtube/search_extractor.rs
* search(query, filter) → SearchInfo { query, corrected_query,
videos, continuation_token }
* Walks twoColumnSearchResultsRenderer → sectionListRenderer →
itemSectionRenderer → videoRenderer (+ shelfRenderer recursion).
* Parses YT duration strings, view-count abbreviations ('1.5M views'),
publishedTimeText, ownerBadges verified flag, badge LIVE flag.
* Music-search filters route to WEB_REMIX — flagged as not-yet-impl.
src/youtube/suggestion_extractor.rs
* suggestions(query) → Vec<String> via the suggestqueries-clients6
endpoint; handles both XSSI-prefixed and bare JSON responses.
src/youtube/channel.rs
* resolve_handle_to_channel_id() via /youtubei/v1/navigation/resolve_url
* channel_info(ChannelIdentifier) → ChannelInfo {
name, description, avatars, banners, subscriber_count, verified,
recent_videos, videos_continuation
}
* Parses both c4TabbedHeaderRenderer (most common) and the newer
pageHeaderRenderer flavor.
* subscriber_count parser handles K/M/B suffixes.
src/youtube/playlist_extractor.rs
* playlist_info(playlist_id) → PlaylistInfo with first-page video
list + continuation_token. Browses with browseId='VL<id>'.
* Walks playlistMetadataRenderer + playlistSidebarRenderer + the
playlistVideoListRenderer.contents[] for video items.
Tests: 121 lib unit pass (+44 since Phase 5). All previous phase smoke
tests still green.
What's left:
* Phase 6 kiosks (Trending etc) — minor, deferred
* Phase 7 — UniFFI surface swap into Straw (Straw repo work)
* Phase 8 — delete rustypipe (Straw repo work)
