Enum Whatsout 

pub enum Whatsout {
    Document,
    Fragment,
    Math,
    Archive,
}

Output extraction mode — port of Perl LaTeXML::Util::Pack’s whatsout option (Pack.pm L320-345). Selects which subtree of the post-processed document to serialize and ship to the user.

• Whatsout::Document — full document, no extraction (default).
• Whatsout::Fragment — embeddable HTML snippet via get_embeddable.
• Whatsout::Math — math subtree (or fallback) via get_math.
• Whatsout::Archive — full document, but bundled into a zip by crate::pack::pack_archive (Pack.pm L326-331 + Pack/Zip.pm::get_archive). Extraction is a no-op; the archiving happens in the binary’s output stage.

Implementations

impl Whatsout

pub fn from_cli(s: &str) -> Option<Self>

Parse a CLI string into the matching variant. Returns None for unrecognized values; callers typically fall back to Document. Mirrors Perl pack_collection’s string-tag dispatch. Perl matches archive with /^archive/, so the archive::zip / archive::zip::perl long forms (Pack/Zip.pm L118-122) also map to Whatsout::Archive.

pub fn as_cli(self) -> &'static str

The canonical CLI tag for this variant — round-trips through Whatsout::from_cli. Used to serialize the mode across a process boundary (the parallel page-render worker manifest).

pub fn is_archive(self) -> bool

Whether this mode bundles the output into a zip archive (Perl pack_collection whatsout =~ /^archive/). The binary’s output stage branches on this to call crate::pack::pack_archive.

pub fn requires_post(self) -> bool

Whether selecting this mode forces post-processing. Perl Config.pm L454: any whatsout other than document implies post = 1 (fragment/math need the extraction stage; archive needs the full post-processed document to bundle).
