infrastructure-ocr-ai

AI-vision OCR engine for infrastructure-ocr-engine: adapts any infrastructure-ai AiProvider (Anthropic vision, Claude CLI, ...) into an OcrEngine. REMOTE by nature — deliberately does NOT implement LocalOcrEngine, so it cannot be used on the DLP screen path.

What it is for

infrastructure-ocr-ai — an AI-vision OcrEngine that adapts any infrastructure-ai AiProvider (Anthropic vision, Claude CLI vision, …) into text recognition.

It sends the image to the provider with an OCR system prompt and returns the provider's transcription.

Deliberately REMOTE — no `LocalOcrEngine`

This adapter transmits the image to a provider (network API, or a CLI that reads a file). It therefore intentionally does NOT implement `infrastructure_ocr_engine::LocalOcrEngine` — so it cannot be constructed into a DLP consumer bounded on E: LocalOcrEngine. That is the whole point of the split: the "never exfiltrate screen pixels" guarantee is enforced by the type system, not a runtime flag. Use this engine for general OCR (documents, catalog scans), never for the DLP screen sensor.

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

Item	What it is
`pub const DEFAULT_OCR_PROMPT: & str`	The default OCR instruction sent as the system prompt.
`pub struct AiVisionEngine`	An `OcrEngine` backed by a `infrastructure-ai` vision provider.
`AiVisionEngine :: fn new(provider : Arc <dyn AiProvider>) -> Self`	Wrap a provider (from `AiProviderFactory` or constructed directly) with the default OCR prompt.
`AiVisionEngine :: fn with_prompt(mut self, prompt : impl Into <String>) -> Self`	Override the OCR system prompt.
`AiVisionEngine :: fn provider_id(& self) -> & 'static str`	—
`AiVisionEngine :: async fn recognize(& self, input : & OcrInput <'_>) -> Result <OcrText, OcrError>`	—

No pub use re-exports: every item above is declared in this crate.

Boundary

Depends on no other workspace tier.

Shares tier infrastructure with 82 other crates: infrastructure-acquire, infrastructure-adapters-google-calendar, infrastructure-adapters-google-gmail, infrastructure-adapters-google-places, infrastructure-adapters-google-trends, infrastructure-adapters-shodan, infrastructure-adapters-yelp, infrastructure-agent, … (82 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Kind	Name	Source

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

Property	Evidence
async public surface	yes
async runtime	none detected
database access	none detected

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

1 workspace crate depends on this one: infrastructure-ocr-provider.
