Enum Attribute 

pub enum Attribute {
    Int(i64),
    Float(f32),
    String(Vec<u8>),
    Ints(Vec<i64>),
    Floats(Vec<f32>),
    Strings(Vec<Vec<u8>>),

}

An ONNX operator attribute. Covers all attribute value kinds.

Variants

Int(i64)

Float(f32)

String(Vec<u8>)

An ONNX STRING attribute. Stored as raw bytes, not String, so that the load/dump path round-trips the payload byte-exactly: ONNX STRING attributes are arbitrary byte strings (e.g. an opaque compiled blob) that are not guaranteed to be valid UTF-8. Use Attribute::as_str to view the bytes as UTF-8 text when that is meaningful.

Ints(Vec<i64>)

Floats(Vec<f32>)

Strings(Vec<Vec<u8>>)

An ONNX STRINGS attribute — a list of raw byte strings (see Attribute::String for why bytes rather than String).

Tensor(TensorData)

Tensors(Vec<TensorData>)

SparseTensor(SparseTensorData)

SparseTensors(Vec<SparseTensorData>)

Graph(Box<Graph>)

A subgraph body (control-flow ops: If/Loop/Scan). Stored inline; the owning Graph also indexes it in subgraphs for traversal.

Graphs(Vec<Graph>)

TypeProto(TypeProto)

TypeProtos(Vec<TypeProto>)

Implementations

impl Attribute

pub fn as_int(&self) -> Option<i64>

The i64 value, if this is an Attribute::Int.

pub fn as_float(&self) -> Option<f32>

The f32 value, if this is an Attribute::Float.

pub fn as_str(&self) -> Option<&str>

The value as UTF-8 text, if this is an Attribute::String whose bytes are valid UTF-8. Returns None for a non-string attribute or for string bytes that are not valid UTF-8 (e.g. an opaque binary payload).

pub fn as_bytes(&self) -> Option<&[u8]>

The raw bytes of an Attribute::String, regardless of whether they are valid UTF-8. Returns None for any other attribute kind.

pub fn as_ints(&self) -> Option<&[i64]>

The &[i64] slice, if this is an Attribute::Ints.

pub fn as_shape(&self) -> Option<Shape>

Interpret an Ints attribute as a shape of static dims.

Trait Implementations

impl Clone for Attribute

fn clone(&self) -> Attribute

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Attribute

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
