Module workspace_index 

Workspace-wide index for cross-file analysis

This module provides infrastructure for rules that need to validate references across multiple files, such as MD051 which validates that cross-file link fragments point to valid headings.

The index is built in parallel and designed for minimal memory overhead.

Cache Format

The workspace index can be persisted to disk for faster startup on repeated runs. The cache format includes a version header to detect incompatible format changes:

[4 bytes: magic "RWSI" - Rumdl Workspace Index]
[4 bytes: format version (u32 little-endian)]
[N bytes: postcard-serialized WorkspaceIndex]
