Enum Processing 

#[non_exhaustive]
pub enum Processing {
    AuthorDate,
    AuthorDateGivenname,
    AuthorDateNames,
    AuthorDateFull,
    Numeric,
    Note,
    Label(LabelConfig),
    Custom(ProcessingCustom),
}

Processing mode for citation/bibliography generation.

Determines how citations and bibliographies are sorted, grouped, and disambiguated. Can be specified as a simple string or with complex configuration maps:

• A string: "author-date", "author-date-full", "numeric", "note", or "label"
• A label config map: { label: { preset: din } }
• A custom config map: { sort: ..., group: ..., disambiguate: ... }

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AuthorDate

Author-date styles (e.g., APA, Chicago). Default bibliography ordering: author, year, title; disambiguates by year suffix.

AuthorDateGivenname

Author-date styles that also add given names during disambiguation.

AuthorDateNames

Author-date styles that also expand name lists during disambiguation.

AuthorDateFull

Author-date styles that expand name lists and add given names during disambiguation.

Numeric

Numeric styles (e.g., IEEE, Nature). Do not imply a bibliography sort; citations are numbered in order of appearance.

Note

Note styles (e.g., Chicago Notes-Bibliography). With a bibliography default to author, title, year ordering.

Label(LabelConfig)

Label styles (e.g., Alpha, DIN 1505-2). Default bibliography ordering: author, year, title.

Custom(ProcessingCustom)

Fully custom processing behavior. Explicit sort configuration remains authoritative.

Implementations

impl Processing

pub fn default_bibliography_sort(&self) -> Option<SortPreset>

Default bibliography sort for the processing family, if any.

Returns the standard bibliography sort order for the processing mode:

• AuthorDate / Label: author, year, title
• Note: author, title, year
• Numeric: None (no automatic sort)
• Custom: the base preset’s default when a base is set and no explicit sort overrides it; otherwise None (an explicit custom sort resolves through config() instead, keeping the entry-ID tiebreak)

pub fn is_author_date_family(&self) -> bool

Returns true for all author-date family variants.

A Custom delta whose base is an author-date preset counts as author-date: a delta on author-date is still an author-date style. Centralizes the author-date family check so new variants don’t require updating scattered matches! blocks across the codebase.

pub fn regime_family(&self) -> RegimeFamily

Coarse citation regime family for cross-regime compatibility checks.

Used during style inheritance to determine whether an inherited parent’s citation-mode sub-specs (integral, non-integral) belong to a different regime and should be reset when the child supplies its own base template.

A base-less Custom is its own family and never triggers automatic sub-spec resets, preserving fully-custom authored styles. A Custom delta with a base belongs to its base’s family: a delta on author-date is still an author-date style.

See docs/specs/CITATION_REGIME.md for the full invariant.

pub fn default_citation_sort_policy(&self) -> CitationSortPolicy

Citation sorting remains explicit-only for all processing families.

All processing modes use ExplicitOnly, meaning citation clusters are only reordered when explicitly configured via citation.sort.

pub fn config(&self) -> ProcessingCustom

Get the effective bibliography/disambiguation configuration for this processing mode.

Returns a ProcessingCustom struct with the resolved configuration combining preset defaults and user overrides. For Custom mode, returns the user-provided config as-is.
