Struct CoalesceChain 

pub struct CoalesceChain {
    pub steps: Vec<CoalesceStep>,
}

Every step of one or-coalescing chain, innermost first.

a or b or c records two steps: [a or b, (that) or c]. A consumer walking the HIR meets the chain root first and descends its left spine, so it consumes this vector back-to-front; the order is fixed here (and only here) so producer and consumer cannot drift.

Fields

steps: Vec<CoalesceStep>

The chain’s steps, innermost first. Never empty.
