Summary

This PR supports StatsError.code and StatsWarning.code. This is an rspack-specific API, which is not implemented in webpack. StatsErrorCode is exported as a reference to code used in rspack.

• ChunkMinificationError: Generated when chunk minification encounters an error
• ChunkMinificationWarning: Generated when chunk minification encounters an warning
• ModuleParseWarning: Generated when module parsing encounters an warning
• ModuleParseError: Generated when module parsing encounters an error
• ModuleBuildError: Generated when module loader encounters an error

The following example shows when minifcation encounters an error:

ERROR in main.js
  × Chunk minification failed:
  ╰─▶   × JavaScript parse error: 'import', and 'export' cannot be used outside of module code
          ╭─[8:0]
        6 │   \******************/
        7 │ (function (module, exports) {
        8 │ import "./abc";
          · ──────
        9 │
       10 │
          ╰────

Its error code is ChunkMinificationError.

trivial changes: Normalize parsing error into parse error. This follows webpack's naming convention, e.g ModuleParseError.

Note: There are a few snapshot changes due to a few newly added snapshot serializer.
