Struct FjSubAtom 

pub struct FjSubAtom {
    pub input_idx: usize,
    pub var_positions: Vec<usize>,
}

One subatom: an atom (input_idx) restricted to the variables its next var_positions.len() physical columns bind/probe. Across the whole plan, each atom’s subatoms consume its columns in order and must partition them exactly (design §3).

Fields

input_idx: usize

Index into the inputs slice of CudaKernelProvider::free_join_execute_u32_recorded.

var_positions: Vec<usize>

Global variable ids bound (cover) or matched (probe) by this subatom’s columns, in column order.
