Struct Bound 

pub struct Bound {
    pub op_index: usize,
    pub description: String,
    pub working_set_size: Option<u64>,
}

A single barrier’s working-set bound.

Fields

op_index: usize

Which IR position the barrier sits at.

description: String

Symbolic description of the barrier (e.g., "ORDER_MATERIALIZE(Halton, indexed=true, n=50)").

working_set_size: Option<u64>

Closed-form working-set size in tuples. None when the size depends on a runtime cardinality (the optimizer’s input is assumed to be V6-rejected if any barrier has unbounded input, so None should not occur for well-formed programs).
