Struct Model 

pub struct Model {
    pub graph: Graph,
    pub metadata: ModelMetadata,
    /* private fields */
}

An owned ONNX model: the shared-IR Graph plus the model-level metadata and (optionally) the live weight store backing external initializers.

Unlike onnx_runtime_loader::Model, which borrows a &Graph, this type owns its graph so it can be returned from load_model, inspected, dumped to text, validated, and written back out.

Fields

graph: Graph

The computation graph, in the shared onnx_runtime_ir IR.

metadata: ModelMetadata

Model-level metadata not carried by the Graph itself.

Implementations

impl Model

pub fn new(graph: Graph) -> Self

Wrap an in-memory Graph as a model with default metadata.

The metadata’s opset_import is still taken from graph.opset_imports at save time; only the header fields (ir_version, producer, …) default.

pub fn with_metadata(graph: Graph, metadata: ModelMetadata) -> Self

Wrap a Graph together with explicit model-level metadata.

pub fn set_weights(&mut self, weights: Arc<WeightStore>)

Attach the live weight store backing external initializers.

pub fn weights(&self) -> Option<&Arc<WeightStore>>

The live weight store, if this model carries one.

pub fn from_proto(proto: ModelProto) -> Result<Self>

Construct a model from the complete generated ONNX protobuf.

The protobuf remains the serialization source of truth, while graph is populated as the runtime-compatible execution projection.

pub fn to_proto(&self) -> Result<ModelProto>

Return the complete generated ONNX protobuf represented by this model.

Models parsed from protobuf JSON/TextFormat return their exact retained schema representation. Programmatically-built models are encoded from the shared runtime graph.

pub fn make_graph_authoritative(&mut self)

Discard the retained source protobuf and make the mutable runtime graph authoritative for future serialization.

Full-spec fields that are not represented by the execution IR (such as training information and local function declarations) cannot survive this transition.

pub fn to_text(&self) -> String

Render this model as a human-readable textual dump (ONNX_RS §5).

pub fn to_text_with(&self, opts: &PrintOptions) -> String

Render this model as text with explicit PrintOptions (ONNX_RS §5.4).

pub fn from_text(source: &str) -> Result<Self>

Parse a model previously rendered in the textual format (ONNX_RS §5.4).

pub fn validate(&self) -> ValidationResult

Validate this model with the default OnnxChecker (ONNX_RS §8).
