Enum ValueType 

pub enum ValueType {
    Tensor(TensorType),
    Sequence(Box<ValueType>),
    Optional(Box<ValueType>),
    Map(DataType, Box<ValueType>),
}

The full type of a value: a tensor, or a container whose element type is itself a ValueType.

ONNX values are tensors in the overwhelming majority of graphs; the tensor path never materialises a ValueType at all (a value with no recorded ValueType is, by construction, a plain tensor). The container variants exist only so Sequence/Optional/Map operators can propagate their element types. This layer is additive: it wraps, and never replaces, TypeInfo, so the tensor-only path stays byte-identical.

Variants

Tensor(TensorType)

A tensor value.

Sequence(Box<ValueType>)

A homogeneous sequence of element-typed values.

Optional(Box<ValueType>)

An optional value that is either present as element or absent.

Map(DataType, Box<ValueType>)

A map from key (an integer or string dtype) to value-typed values.

Implementations

impl ValueType

pub fn tensor(dtype: DataType, shape: TypedShape) -> Self

pub fn as_tensor(&self) -> Option<&TensorType>

The tensor leaf, when this value is a tensor.

pub fn as_sequence_element(&self) -> Option<&ValueType>
