Nodes

Nodes

src/nodes.rs — closed NirNode enum. Wire names via type_name() must match io::wire::WIRE_TYPES.

Wire types (19)

Wire string	Variant
Input	NirNode::Input
Output	NirNode::Output
Affine	Affine
Linear	Linear
Scale	Scale
Conv1d / Conv2d	Conv1d / Conv2d
CubaLI / CubaLIF	CubaLi / CubaLif
Delay	Delay
Flatten	Flatten
I / IF / LI / LIF	I / If / Li / Lif
SumPool2d / AvgPool2d	pooling
Threshold	Threshold
NIRGraph	nested Graph(Box<NirGraph>)

Upstream Identity is intentionally absent (not in Python serializer registry).

Aliases that are NOT wire types

Reject / never write: CurrLIF, Convolution, Integrator, SumPooling, …

Optional fields

Examples: v_reset, w_in may be absent on wire; reader fills Python-compatible defaults so in-memory graphs match nir.read.

Padding

Symbolic modes "same" / "valid" as strings; explicit integer padding as arrays.
