Summary of Changes
Hello @siq1, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request is a significant documentation effort aimed at improving the clarity and understanding of the Expander Compiler's codebase. It introduces extensive Rustdoc comments across multiple modules, clarifies the purpose of key data structures and functions, and cleans up obsolete inline comments. Additionally, it formally deprecates an older builder module, guiding future development towards more optimized alternatives.
Highlights
- Documentation Improvements: Added comprehensive Rustdoc comments (
//!and///) to modules, structs, enums, traits, and functions across theec_go_lib,macros,builder,circuit,compile,frontend,hints,layering, andutilscrates. These comments explain the purpose, usage, and internal workings of various components, significantly enhancing code readability and maintainability. - Code Cleanup: Removed several outdated or redundant inline comments and block comments, particularly within the
macrosandbuilder/basic.rsfiles, streamlining the codebase. - Deprecation Notices: Marked the
expander_compiler/src/builder/final_build.rsmodule and its associatedBuildertype alias andprocessfunction as#[deprecated], indicating that this part of the code is no longer recommended for use and will be removed in the future. Also added#[allow(deprecated)]where necessary to suppress warnings. - Refined Data Structure Explanations: Enhanced documentation for core data structures like
RootBuilder,Builder,OutVarRef,ConstraintStatus,LinMeta,InsnTransformResult,Coef,InputMapping,VarSpec,Term,Expression,LinComb,Witness,Gate,Segment, andCircuitto provide clearer understanding of their roles and relationships within the compiler's IR and layered circuit representations. - Clarified API and Compilation Steps: Added detailed explanations for API traits (
BasicAPI,UnconstrainedAPI,RootAPI) and their methods, as well as for the various compilation steps and their options (CompileOptions), improving the clarity of the compiler's external interfaces and internal processes.

Code Review
This pull request adds a significant amount of documentation across the codebase, which greatly improves readability and maintainability. The added comments are clear and helpful. I've found one minor issue with incorrect doc comments for a struct's fields, likely due to a copy-paste error, and have provided a suggestion to fix it. Overall, this is a great contribution to the project's documentation.

| /// The segments in the circuit. | ||
| pub layer_ids: Vec<usize>, |

The documentation for segments and layer_ids appears to be incorrect. The comment for segments seems to be a copy-paste error, and the comment for layer_ids actually describes segments.
| /// The number of expected output ones in the circuit. | |
| pub segments: Vec<Segment<C, I>>, | |
| /// The segments in the circuit. | |
| pub layer_ids: Vec<usize>, | |
| /// The segments in the circuit. | |
| pub segments: Vec<Segment<C, I>>, | |
| /// The IDs of the layers in the circuit, in order of execution. | |
| pub layer_ids: Vec<usize>, |
