refactor(eval): split compiler.rs into module directory#53
Merged
Conversation
Modularize the 1824-line compiler.rs into focused submodules for
maintainability. No behavior changes; identical test results
(366 unit tests pass).
New structure:
compiler/
mod.rs -- types, compilation, evaluation logic
helpers.rs -- encoding, regex, pattern matching utilities
tests.rs -- all unit and property tests

Both the ASCII diagram in README.md and the Mermaid diagram in
assets/architecture.mmd lagged the codebase by several releases. Update
them to reflect:
- Dynamic Sigma Pipelines (v0.10.0): new sources/ subsystem inside
rsigma-runtime with SourceResolver, TemplateExpander, SourceCache,
RefreshScheduler, extract languages (jq, JSONPath, CEL), and the
flow back into the eval pipeline via ${source.*} template expansion.
- Matcher optimizer and eval prefilters (v0.11.0): Aho-Corasick and
RegexSet batching plus CaseInsensitiveGroup inside compiler/, and
the prefilter layers (RuleIndex, bloom trigram filter, cross-rule
AC index via daachorse) inside engine/.
- DLQ as a sink target and broaden hot-reload to rules + pipelines.
- Builtin pipelines (ecs_windows, sysmon).
- Rename single-file module references (compiler.rs, engine.rs,
correlation.rs) to the directory module style that landed in the
v0.9.0 modularization PRs (#53, #54, #55).
- Add a legend explaining * = feature-gated and ** = requires the
daachorse-index feature.
