Module store 

EdgeId and the insertion-ordered map keyed by it. EdgeId is presentation’s own: the router never persists edge identity, so nothing outside this module allocates one.

Collections are plain IdMaps (IndexMap with a fast hasher); iteration follows insertion order, which is semantically meaningful (render z-order, route-crossing priority, hit-test).

Structs

EdgeId

A router edge’s id. The router never persists edge identity, so this is minted and read only within this module; it renders as "e" + a counter (the family every id newtype in the snapshot-era store used) purely for consistency with IdMapExt::insert_value’s counter-based minting.

Traits

IdMapExt

Operations on an IdMap that IndexMap does not provide directly.

KeyType

Keys usable in an IdMap.

Type Aliases

IdMap

An insertion-ordered map keyed by an id newtype, backed by IndexMap with a fast (non-DoS-resistant) hasher. Iteration follows insertion order, which is semantically meaningful (render z-order, route-crossing priority).
