描述

We use integers as keys in many places (procotol and examples) but usually without a custom key serialization. As a result, graphql queries show keys ordered by little-endian bytes.

See AskPrice and BidPrice in the matching engine example.

研究方向
Examine the matching engine example in the Linera protocol repository, specifically the AskPrice and BidPrice types. Look at how they currently use integer keys without custom serialization, resulting in little endian byte ordering in GraphQL queries. Study the existing CustomMapView and CustomCollectionView implementations to understand the pattern. The task is to create new example views that serialize ordered integers correctly, then integrate them into the matching engine or another appropriate location. Refer to the relevant source files in the examples directory and the views module to determine the exact files and structures involved.
