Rustlens

A blazing-fast Rust code inspector for the terminal. Rustlens is a terminal-based application for exploring Rust codebases. It parses your Rust source files and provides an interactive interface to browse functions, structs, enums, traits, and more — all without leaving your terminal. Built with Ratatui for a smooth, responsive TUI experience.

Features

• Code Analysis — Parses Rust source files using syn:

  • Functions (parameters, return types, async/const/unsafe)
  • Structs (fields, derives, generics)
  • Enums (variants with all field types)
  • Traits (methods, associated types, supertraits)
  • Impl blocks (inherent and trait implementations)
  • Modules, Type aliases, Constants, Statics

• Smart Search — Fuzzy matching with real-time filtering

• Dependency Analysis — Visualize Cargo.toml dependencies

• Multiple Themes — Default Dark, Nord, Catppuccin Mocha, Dracula

• Smooth Animations — Selection highlights, tab transitions

• Vim-style Navigation — j/k for movement, / for search

# Cd into the project directory
cd path/to/rust-project
