Rust

User preferences and memory live in ~/Clawic/data/rust/ (see setup.md on first use, memory-template.md for the file format). If you have data at an old location (~/rust/ or ~/clawic/rust/), move it to ~/Clawic/data/rust/.

When To Use

• Writing or reviewing Rust: functions, traits, error types, async code, public crate APIs
• Fighting the compiler: moves, borrows, lifetimes, trait bounds, dyn compatibility, type inference
• Diagnosing runtime failures: panics, deadlocks, BorrowMutError, memory growth, segfaults through unsafe or FFI
• Cargo work: features, workspaces, lockfiles, MSRV, slow builds, CI-only failures, duplicated dependencies
• Targets beyond the host: cross-compilation, static musl binaries, no_std firmware, wasm
• Not for C++ (cpp) or language-agnostic concurrency theory (async-patterns) — this is Rust the language and its toolchain
