Flowistry is a Rust IDE plugin (VS Code extension plus rustc plugin) that performs modular information flow analysis to determine which code can affect which. Its 'focus mode' fades out code unrelated to the selected variable or expression, aiding comprehension of large functions.
Use cases
- understand which parts of a Rust function affect a given variable
- read and comprehend large unfamiliar Rust codebases
- filter out irrelevant code while debugging
- analyze dataflow and dependencies between expressions in Rust
- identify the influence of a function argument
- explore information flow in compiler internals
When to choose
- you work in Rust and struggle to trace influence between variables in large functions
- you want IDE-integrated static dataflow analysis for code reading
- you need a research-backed information flow tool for Rust
When to avoid
- you need analysis across nested functions, closures, or async code
- your code relies heavily on interior mutability
- you use an IDE other than VS Code or need language-agnostic support
