Crate ezu_graph 

Typed DAG evaluator for the Ezu Style Spec.

• port — PortKind, PortSpec, CoordSpace
• buf / value — concrete buffers and the PortValue enum
• node — the Node trait every operation implements
• graph — GraphBuilder / Graph with topo sort, type checking, cycle detection, and pad propagation
• registry / build — turn a parsed ezu_style::Document into a typed Graph using a registry of node factories
• eval / cache / evaluator — render a tile

Modules

buf

Concrete buffer types flowing along Raster edges.

build

Drive GraphBuilder from a parsed spec::Document using a NodeRegistry.

cache

Render-time intermediate cache, keyed by a content-derived hash.

eval

Evaluation context, asset loader, and error types used during Node::eval.

evaluator

Walk the DAG and evaluate one tile.

graph

The DAG itself: building, type-checking, topology, pad propagation.

node

The Node trait — what every operation in the graph implements.

port

Port kinds — the type system of the DAG.

registry

Node registry — maps op names to factory functions.

value

PortValue — the runtime values flowing along DAG edges.

Macros

submit_node

Submit a unit-struct NodeFactory to the global inventory so NodeRegistry::from_inventory picks it up.
