OCA SDK

Comprehensive SDK for OCA Bundle management and integration in Rust.

This crate helps you:

• parse OCAfiles,
• build and validate OCA bundles,
• validate captured data against bundles,
• load/serialize bundles and overlays.

Usage (library)

Add to your Cargo.toml:

oca-sdk-rs = "2.0.0-rc.5"

Creating a Bundle from OCAFile

use oca_sdk_rs::oca::overlay_file::OverlayLocalRegistry;
use oca_sdk_rs::oca::file::parse_from_string;
use oca_sdk_rs::oca::bundle::from_ast;

let overlay_registry = OverlayLocalRegistry::from_dir("path/to/overlay-files")?;
let ocafile_str = std::fs::read_to_string("path/to/ocafile.ocafile")?;
let oca_ast = parse_from_string(ocafile_str, &overlay_registry)?;
let oca_bundle = from_ast(None, &oca_ast)?.oca_bundle;

Validating Bundle Semantics

use oca_sdk_rs::oca::bundle::{validate_semantics, SemanticValidationStatus};

let status = validate_semantics(&oca_bundle)?;
assert!(matches!(status, SemanticValidationStatus::Valid));

Validating Captured Data

use oca_sdk_rs::oca::validator::validate_data;

let data = serde_json::from_str(r#"{"field": "value"}"#)?;
let validation_status = validate_data(&mut oca_bundle, &data)?;

Accessing Bundle Attributes

use oca_sdk_rs::oca::bundle::{OCABundleModel, WithInfo};

let info = oca_bundle.model.info();
for attr in info.attributes() {
    println!("{:?}", attr);
}

Converting Bundle to JSON

use oca_sdk_rs::oca::bundle::{OCABundleModel, ToJSON};

let json = oca_bundle.model.get_json_bundle();
println!("{}", json);

Tests

Integration tests must live directly under tests/ (for example tests/captured_data_validation.rs). Files placed in subdirectories like tests/assets/ are treated as fixtures/modules and will not be picked up by Cargo automatically.

Examples

Run any example with:

cargo run --example <name>

Available examples:

• build_from_ocafile — parse an ocafile and build a bundle
• validate_semantics — validate semantics for a bundle JSON
• validate_data — validate captured JSON data
• load_bundle_json — load an existing bundle JSON
• generate_ocafile — convert a bundle JSON back to ocafile

Notes:

• Examples use fixtures under tests/assets/ (paths are relative to the crate root).
• If you run from a different working directory, use absolute paths or cargo run --example <name> -- <args>.
