Module tree 

In-memory tree representation and full-tree wire format.

See docs/PROTOCOL.md § “Tree representation” for the wire spec. Each node line is:

<ref> <role> <label> [op[,op]...] [k=v]...

…prefixed by two spaces of indent per nesting level. The encoder emits a canonical form (attributes sorted alphabetically, ops in source order via std::collections::BTreeSet); the parser is tolerant of either ordering.

Structs

Node

One node in the a11y tree.

Ref

A stable session-scoped element identifier. Refs are positive integers; 0 is reserved as the wire sentinel for “root level” in delta operations.

Tree

A full a11y tree as exchanged on the wire.

TreeIter

Pre-order iterator over a tree.
