    pub schema_version: String,
    pub title: String,

}

Metadata for a single stored entry.

Reserved top-level fields per docs/STORE.md §2. schema_version is a string of the form <MAJOR>.<MINOR>; the current version this build writes is crate::SCHEMA_VERSION.

Unknown top-level fields and unknown tables are preserved verbatim through the other field, so reading-and-rewriting an entry produced by a future minor revision (or by BiblioFetch.jl) does not silently drop data.

Fields

schema_version: String

Schema version of the form <MAJOR>.<MINOR>. See docs/STORE.md §3.

title: String

Paper title.

authors: Vec<String>

List of authors (preserve original ordering).

year: Option<i32>

Publication year, if known.

doi: Option<Doi>

DOI, if any.

arxiv_id: Option<ArxivId>

arXiv id, if any.

arxiv_categories: Vec<String>

arXiv subject categories in feed order (e.g. ["cond-mat.str-el", "cond-mat.dis-nn"]); the first is the primary class. Populated from the Atom feed <category term="…"> elements so cite / bib can emit a complete arXiv BibTeX entry (primaryClass, issue #303). Additive optional field — does not bump schema_version (docs/STORE.md §7 additive policy); omitted from the TOML when empty.

abstract_: Option<String>

Abstract; serialized as the bare abstract key (Rust keyword).

venue: Option<String>

Venue (e.g. journal or conference).

volume: Option<String>

Volume (journal articles). Crossref volume.

issue: Option<String>

Issue number (journal articles). Crossref issue; rendered as the BibTeX number field and the CSL issue field.

pages: Option<String>

Page range (e.g. 477--528). Crossref page.

publisher: Option<String>

Publisher.

issn: Option<String>

ISSN (for journals).

isbn: Option<String>

ISBN (for books).

type_: Option<String>

Crossref-taxonomy type. Serialized as the bare type key.

keywords: Vec<String>

Free-form keywords.

url: Option<String>

Canonical URL for the entry, if any.

pdf_path: Option<String>

Path to the stored PDF, relative to the store root.

doiget: Option<DoigetExtension>

doiget-specific extension table. BiblioFetch.jl ignores it.

other: BTreeMap<String, Value>

All other top-level keys and tables (e.g. [bibliofetch]).

Per docs/STORE.md §8 we MUST tolerate unknown top-level fields and unknown tables. Unknown entries are captured here so a read / modify / write cycle does not silently drop them. Keys are stored in a BTreeMap so re-serialization is alphabetically ordered, matching the normalization rule in docs/STORE.md §7.

Trait Implementations

impl Debug for Metadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Metadata

fn default() -> Metadata

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Metadata
