Enum DocumentFormat 

pub enum DocumentFormat {
    Pdf,
    Docx,
    Epub,
    Odt,
    Ods,
    Odp,
    Xlsx,
    Pptx,
    Json,
    Yaml,
    Opaque,
}

A detected document format (the class of the field’s source bytes).

Variants

Pdf

A validated PDF (physical indicators).

Docx

An OPC package with a WordprocessingML officeDocument part.

Epub

An OCF container with an EPUB package document.

Odt

An ODF package with an OpenDocument text content part.

Ods

An ODF package with an OpenDocument spreadsheet content part.

Odp

An ODF package with an OpenDocument presentation content part.

Xlsx

An OPC package with a SpreadsheetML workbook part.

Pptx

An OPC package with a PresentationML presentation part.

Json

A structured JSON document (the whole source parses as exactly one JSON value). Not a package: the exact leaf is the whole source (Phase 21.5.1).

Yaml

A structured YAML document (the whole source parses as a bounded YAML stream whose every document root is a mapping or a sequence). Not a package: the exact leaf is the whole source (Phase 21.6.1).

Opaque

Anything else; preserved exactly by the opaque floor.

Implementations

impl DocumentFormat

pub const fn name(self) -> &'static str

Stable lower-case name (used in JSON and in the manifest provenance token).

pub const fn adapter(self) -> &'static str

The adapter that serves this format (the observation layer’s name for it).

pub const fn compiled(self) -> bool

Whether the adapter for this format is compiled into this build.

pub fn provenance_prefix(self) -> String

The machine-readable format=<name>; provenance prefix recorded at ingest.

pub fn from_provenance(provenance: &str) -> Option<DocumentFormat>

Recover the recorded format from a field manifest’s provenance string.

Returns None for a manifest that does not carry the token (e.g. a field written before this subphase); such a field still serves every native selector, but common observations decline typed rather than guessing.
