Struct FusionChain 

pub struct FusionChain {
    pub expr: FusedExpr,
    pub sources: Vec<Local>,
    pub result_local: Local,
    pub elem_c: String,
    pub rank: u32,
    pub eliminated_locals: Vec<Local>,
}

A fusion opportunity: a chain of element-wise ops that can be fused.

Fields

expr: FusedExpr

The fused expression tree

sources: Vec<Local>

Source array locals (in order of Source(0), Source(1), …)

result_local: Local

The result local where the fused output is stored

elem_c: String

The element type (C identifier, e.g. “double”)

rank: u32

Rank of the ndarray

eliminated_locals: Vec<Local>

Intermediate locals that can be eliminated after fusion
