Struct FusionRule 

pub struct FusionRule {
    pub name: &'static str,
    pub pattern: FusionPattern,
    pub replacement: fn(&MatchResult) -> Box<dyn PolydatNode>,
    pub input_bindings: &'static [&'static str],
}

A graph rewrite rule: a subgraph pattern and its replacement.

Each rule is a declarative specification. The pattern describes what to match; the replacement factory produces the fused node; input_bindings maps the fused node’s input ports to captured wire sources by name.

Fields

name: &'static str

Human-readable name for diagnostics, logging, and test output.

pattern: FusionPattern

The subgraph pattern to match.

replacement: fn(&MatchResult) -> Box<dyn PolydatNode>

Factory: given the match result, produce the replacement fused node.

input_bindings: &'static [&'static str]

Binding names for the fused node’s inputs, in order. Each name must correspond to an Any leaf in the pattern.
