Trailing Comma Issues in Struct Definitions +**Problem**: Generated invalid syntax like `pub struct SimpleFormerStorage < 'a, >` +**Solution**: Created clean versions of all generic parameter lists for struct definitions: + +```rust +// Create clean versions without trailing commas for struct definitions +let mut struct_generics_with_defaults_clean = struct_generics_with_defaults.clone(); +while struct_generics_with_defaults_clean.trailing_punct() { + struct_generics_with_defaults_clean.pop_punct(); +} +``` + +Applied to: +- `SimpleFormerStorage` +- `SimpleFormer` +- `SimpleFormerDefinition` +- `SimpleFormerDefinitionTypes` + +**Result**: All struct definitions now have clean generic parameters without trailing commas + +#### C.

workspace-relative path resolution in Rust. + +## What is workspace_tools? + +workspace_tools solves a fundamental problem that every Rust developer encounters: **reliable path resolution that works regardless of where your code runs**. + +### The Problem + +```rust +// โŒ These approaches are fragile and break easily: + +// Relative paths break when execution context changes +let config = std::fs::read_to_string("../config/app.toml")?; + +// Hardcoded paths aren't portable +let data = std::fs::read_to_string("/home/user/project/data/cache.db")?; + +// Environment-dependent solutions require manual setup +let base = std::env::var("PROJECT_ROOT")?; +let config = std::fs::read_to_string(format!("{}/config/app.toml", base))?; +``` + +### The Solution + +```rust +// โœ… workspace_tools provides reliable, context-independent paths: + +use workspace_tools::workspace; + +let ws = workspace()?; +let config = std::fs::read_to_string(ws.join("config/app.toml"))?; +let data = std::fs::read_to_string(ws.data_dir().join("cache.db"))?; + +// Works perfectly whether called from: +// - Project root: cargo run +// - Subdirectory: cd src && cargo run +// - IDE debug session +// - CI/CD pipeline +// - Container deployment +``` + +## Why workspace_tools? + +### ๐ŸŽฏ **Zero Configuration** +Works immediately with Cargo workspaces. No setup files needed. + +### ๐Ÿ—๏ธ **Standard Layout** +Promotes consistent, predictable project structures across the Rust ecosystem. + +### ๐Ÿ”’ **Security First** +Built-in secrets management with environment fallbacks. + +### โšก **High Performance** +Optimized for minimal overhead, scales to large monorepos. + +### ๐Ÿงช **Testing Ready** +Isolated workspace utilities make testing straightforward. + +### ๐ŸŒ **Cross-Platform** +Handles Windows/macOS/Linux path differences automatically. + +### ๐Ÿ“ฆ **Framework Agnostic** +Works seamlessly with any Rust framework or architecture. + +## Who Should Use This? + +- **Application Developers**: CLI tools, web services, desktop apps +- **Library Authors**: Need reliable resource loading +- **DevOps Engineers**: Container and CI/CD deployments +- **Team Leads**: Standardizing project structure across teams +- **Students & Educators**: Learning Rust best practices + +## Quick Preview + +Here's what a typical workspace_tools project looks like: + +``` +my-project/ +โ”œโ”€โ”€ Cargo.toml +โ”œโ”€โ”€ src/ +โ”‚ โ””โ”€โ”€ main.rs +โ”œโ”€โ”€ config/ # โ† ws.config_dir() +โ”‚ โ”œโ”€โ”€ app.toml +โ”‚ โ””โ”€โ”€ database.yaml +โ”œโ”€โ”€ data/ # โ† ws.data_dir() +โ”‚ โ””โ”€โ”€ cache.db +โ”œโ”€โ”€ logs/ # โ† ws.logs_dir() +โ””โ”€โ”€ tests/ # โ† ws.tests_dir() + โ””โ”€โ”€ integration_tests.rs +``` + +```rust +// src/main.rs +use workspace_tools::workspace; + +fn main() -> Result<(), Box> { + let ws = workspace()?; + + // Load configuration + let config_content = std::fs::read_to_string( + ws.config_dir().join("app.toml") + )?; + + // Initialize logging + let log_path = ws.logs_dir().join("app.log"); + + // Access data directory + let cache_path = ws.data_dir().join("cache.db"); + + println!("โœ… Workspace initialized at: {}", ws.root().display()); + Ok(()) +} +``` + +## What's Next? + +Ready to get started?

It rejects rigid, all-or-nothing frameworks in favor of flexible, composable tools that integrate seamlessly into your existing workflow. + +## The Benchmarking Dilemma + +In Rust, developers often face a frustrating choice: + +1. **The Heavy Framework (`criterion`):** Statistically powerful, but forces a rigid structure (`benches/`), complex setup, and produces reports that are difficult to integrate into your project's documentation. You must adapt your project to the framework. +2. **The Manual Approach (`std::time`):** Simple to start, but statistically naive. It leads to boilerplate, inconsistent measurements, and conclusions that are easily skewed by system noise. + +`benchkit` offers a third way. + +## A Toolkit, Not a Framework + +This is the core philosophy of `benchkit`. It doesn't impose a workflow; it provides a set of professional, composable tools that you can use however you see fit. + +* โœ… **Integrate Anywhere:** Write benchmarks in your test files, examples, or binaries. No required directory structure. +* โœ… **Documentation-First:** Treat performance reports as a first-class part of your documentation, with tools to automatically keep them in sync with your code. +* โœ… **Practical Focus:** Surface the key metrics needed for optimization decisions, hiding deep statistical complexity until you ask for it. +* โœ… **Zero Setup:** Start measuring performance in minutes with a simple, intuitive API. + +--- + +## ๐Ÿš€ Quick Start: Compare, Analyze, and Document + +This example demonstrates the core `benchkit` workflow: comparing two algorithms and automatically updating a performance section in your `readme.md`. + +**1.

Use only what you need. + +
+Measure: Core Timing and Profiling + +At its heart, `benchkit` provides simple and accurate measurement primitives. + +```rust +use benchkit::prelude::*; + +// A robust measurement with multiple iterations and statistical cleanup. +let result = bench_function +( + "summation_1000", + || + { + ( 0..1000 ).fold( 0, | acc, x | acc + x ) + } +); +println!( "Avg time: {:.2?}", result.mean_time() ); +println!( "Throughput: {:.0} ops/sec", result.operations_per_second() ); + +// Track memory usage patterns alongside timing. +let memory_benchmark = MemoryBenchmark::new( "allocation_test" ); +let ( timing, memory_stats ) = memory_benchmark.run_with_tracking +( + 10, + || + { + let data = vec![ 0u8; 1024 ]; + memory_benchmark.tracker.record_allocation( 1024 ); + std::hint::black_box( data ); + } +); +println!( "Peak memory usage: {} bytes", memory_stats.peak_usage ); +``` + +
+ +
+Analyze: Find Insights and Regressions + +Turn raw numbers into actionable insights. + +```rust +use benchkit::prelude::*; + +// Compare multiple implementations to find the best one. +let report = ComparativeAnalysis::new( "Hashing" ) +.algorithm( "fnv", || { /* ... */ } ) +.algorithm( "siphash", || { /* ... */ } ) +.run(); + +if let Some( ( fastest_name, _ ) ) = report.fastest() +{ + println!( "Fastest algorithm: {}", fastest_name ); +} + +// Example benchmark results +let result_a = bench_function( "test_a", || { /* ... */ } ); +let result_b = bench_function( "test_b", || { /* ... */ } ); + +// Compare two benchmark results +let comparison = result_a.compare( &result_b ); +if comparison.is_improvement() +{ + println!( "Performance improved!" ); +} +``` + +
+ +
+Generate: Create Realistic Test Data + +Stop writing boilerplate to create test data. `benchkit` provides generators for common scenarios. + +```rust +use benchkit::prelude::*; + +// Generate a comma-separated list of 100 items. +let list_data = generate_list_data( DataSize::Medium ); + +// Generate realistic unilang command strings for parser benchmarking. +let command_generator = DataGenerator::new() +.complexity( DataComplexity::Complex ); +let commands = command_generator.generate_unilang_commands( 10 ); + +// Create reproducible data with a specific seed. +let mut seeded_gen = SeededGenerator::new( 42 ); +let random_data = seeded_gen.random_string( 1024 ); +``` + +
+ +
+Document: Automate Your Reports + +The "documentation-first" philosophy is enabled by powerful report generation and file updating tools. + +```rust +use benchkit::prelude::*; + +fn main() -> Result< (), Box< dyn std::error::Error > > +{ + let mut suite = BenchmarkSuite::new( "api_performance" ); + suite.benchmark( "get_user", || { /* ... */ } ); + suite.benchmark( "create_user", || { /* ... */ } ); + let results = suite.run_analysis(); + + // Generate a markdown report from the results. + let markdown_report = results.generate_markdown_report().generate(); + + // Automatically update the "## Performance" section of a file. + let updater = MarkdownUpdater::new( "readme.md", "Performance" ); + updater.update_section( &markdown_report )?; + + Ok( () ) +} +``` + +
+ +## The `benchkit` Workflow + +`benchkit` is designed to make performance analysis a natural part of your development cycle. + +```text +[ 1. Write Code ] -> [ 2. Add Benchmark in `tests/` ] -> [ 3. Run `cargo test` ] + ^ | + | v +[ 5. Commit Code + Perf Docs ] <- [ 4.

Markdown-First Integration +- **Problem**: Manual copy-pasting of performance results into documentation +- **Solution**: Automated markdown section updating with version control friendly output +- **Evidence**: Frequent need to update README performance sections during optimization + +#### 9.3. Standard Data Size Patterns +- **Problem**: Inconsistent data sizes across different benchmarks made comparison difficult +- **Solution**: Standardized DataSize enum with proven effective sizes +- **Evidence**: "Common patterns: small (10), medium (100), large (1000), huge (10000)" + +#### 9.4.
