Class BundledOnnxModelSource

Namespace

Qavren.Edge.Onnx

Assembly

Qavren.Edge.Onnx.dll

An app-packaged asset, copied out once. The opener is the consumer's - in MAUI that is FileSystem.OpenAppPackageFileAsync - so this package never references MAUI.

Remarks

The copy is unavoidable. On Android a MauiAsset is an AssetManager stream with no path and no length, and spec 9.1 requires a real path: a byte-array session doubles transient memory and degrades ORT's CoreML cache key from the model-URL hash to a hash of graph inputs and node outputs, which collides across quantization variants of one architecture.

Constructors

BundledOnnxModelSource(IEdgeModelPaths, Func<string, CancellationToken, ValueTask<Stream>>)

Creates the source.

Properties

Name

A short stable name, used in logs and in provisioning failures.

Methods

CanProvide(OnnxModelManifest)

Whether this source could supply the manifest at all. Cheap and synchronous: it inspects the manifest, never the network.

EnsureAsync(OnnxModelManifest, IProgress<ModelProvisioningProgress>?, CancellationToken)

Materialises every file into <Models>/<modelId>/<sha16>, verifying each digest, and returns the resolved paths.
