# Rust Toolchain Setup

**Workstation:** Cal's Linux workstation

## Installation

Rust installed via `rustup` — current version **v1.93.1** (as of 2026-02-28).

## Fish Shell PATH

For fish shell, source the env file to activate cargo in PATH:

```fish
source ~/.cargo/env.fish
```

Rustup auto-configures fish via `~/.config/fish/conf.d/` so this may already be active in new shells.

## Build Cache

Cargo stores compiled artifacts in `target/` directory. Incremental builds only recompile changed files, so subsequent builds are significantly faster than the first.
