Struct ExactPlan 

pub struct ExactPlan {
    pub range: ExactRange,
    pub lengths: Vec<usize>,
    pub total: usize,
}

What an exact stage needs: the range of its leaves and the size of its temporaries.

Fields

range: ExactRange

The magnitudes of the leaves for which the stage is valid.

lengths: Vec<usize>

The worst-case length of the expansion of each node, in the order of the graph: 1 or 2 for a leaf (see Leaves), 1 for a nonzero constant and 0 for zero, l_x + l_y for a sum or difference, 2 l_x l_y for a product and l_x for a negation.

total: usize

The sum of lengths: the size of all the temporaries, each shared node counted once.
