Struct CppComparableParameter 

pub struct CppComparableParameter { /* private fields */ }

A parameter type as a flat arena of nodes plus a root index.

The arena carries the same rationale as StructuredTypeIdentity: source can nest types very deeply, and cloning, comparing or dropping the value must not consume the Rust call stack. Nodes are appended in post-order, so every child index is smaller than its parent’s and the last appended node is the root.

That post-order append is also what makes the derived PartialEq a correct structural equality: the builder below is deterministic, so one type shape has exactly one arena layout no matter which spelling produced it. Two shapes are equal as values iff they are equal as type trees.
