Struct FixtureOcrBackend 

pub struct FixtureOcrBackend { /* private fields */ }

Fixture-driven OCR backend for tests and local scaffolding.

This backend returns pre-registered OCR results keyed by exact file path, file name, or file stem (in that order). It is intended for ingestion pipeline development when native OCR runtimes are unavailable.

Implementations

impl FixtureOcrBackend

pub fn new() -> Self

Create an empty fixture backend using the mock engine label.

pub fn with_engine(engine: OcrEngine) -> Self

Create an empty fixture backend with a custom engine label.

pub fn with_document( self, key: impl Into<String>, document: OcrDocument, ) -> Self

Register a fixture document for a given path-like lookup key.

The key can be:

• exact path string
• file name (e.g., Screenshot.png)
• file stem (e.g., Screenshot)

pub fn with_default_document(self, document: OcrDocument) -> Self

Register a default fixture returned when no key-specific fixture exists.
