Struct Census 

pub struct Census<'v, 's, S: RangeSource> { /* private fields */ }

Retains every original member role in CD order, including duplicates, reserved names and unreadable members. One pooled name buffer remains in the archive; this catalogue stores only fixed-size classifications.

Implementations

impl<'v, 's, S: RangeSource> Census<'v, 's, S>

pub fn read<W: Work>( archive: &'v Archive<'s, S>, work: &W, ) -> Result<Self, Error<S::Error>>

Performs a paid metadata pass under both the source and current query.

Panics

An internal catalogue invariant fails if a bounded original ordinal is absent.

pub fn archive(&self) -> &'v Archive<'s, S>

The complete immutable ZIP occurrence census.

pub fn len(&self) -> usize

Number of original members, never the number of unique names.

pub fn is_empty(&self) -> bool

Whether the original census is empty.

pub fn occurrence<W: Work>( &self, ordinal: usize, work: &W, ) -> OccurrenceResult<'v, 's, S>

Selects one original occurrence and its paid role under this query.

pub fn mimetypes<'q, W: Work>( &'q self, work: &'q W, ) -> impl Iterator<Item = SourceResult<MimetypeHeader<<S as RangeSource>::Document, <S as RangeSource>::Generation>, S>> + use<'q, 'v, 's, S, W>

Complete mimetype occurrence traversal. Failure fuses this query, and an absent optional member never becomes a fabricated default media type.
