Cargo Rust Skill

Trit: -1 (MINUS - build verification and constraint checking)
Foundation: Cargo + rustc + crates.io

Core Concept

Cargo manages Rust projects with:

• Dependency resolution
• Build orchestration
• Testing and benchmarking
• Publishing to crates.io

Commands

# Build
cargo build
cargo build --release

# Test
cargo test
cargo test --lib

# Check (fast)
cargo check
cargo clippy

# Run
cargo run
cargo run --release

# Add dependency
cargo add serde
cargo add serde --features derive

Workspace Pattern

# Cargo.toml (workspace root)
[workspace]
members = ["crates/*"]
resolver = "2"

[workspace.dependencies]
serde = { version = "1.0", features = ["derive"] }

GF(3) Integration

fn trit_from_build(result: &BuildResult) -> i8 {
    match result {
        BuildResult::Error(_) => -1,   // MINUS: compilation failure
        BuildResult::Warning(_) => 0,  // ERGODIC: warnings
        BuildResult::Success => 1,     // PLUS: clean build
    }
}
