Summary

Compiling Rust source code into executable binaries and libraries using cargo, the Rust package manager. This skill is essential for constructing command-line tools and libraries for scientific data format conversion and validation.

When to use

When you have Rust source code (such as the mzPeak format implementation at the repository root) and need to generate executable binaries or libraries for converting mass-spectrometry file formats, validating output files, or reading/writing domain-specific formats like mzPeak.

When NOT to use

• Input is already a pre-compiled binary or distributed package—skip to execution instead of rebuilding
• Rust toolchain is not installed or target platform lacks required system libraries—install prerequisites first
• You only need to read or inspect source code without execution—use a text editor or code browser instead

Inputs

• Rust source code repository with Cargo.toml manifest
• Rust version (typically 1.56 or later)
• System libraries and development headers required by dependencies

Outputs

• Compiled executable binaries in target/debug/ or target/release/
• Static or dynamic libraries (.rlib, .so, .dylib, .dll)
• Intermediate build artifacts in target/ directory

How to apply

Clone or access the target Rust repository containing the source code and Cargo.toml manifest. Execute cargo build (or cargo build --release for optimized production binaries) from the repository root to compile all dependencies and source code into an executable. The build process resolves dependencies declared in Cargo.toml, compiles them in the correct order, and produces binaries in the target/ directory. Verify successful compilation by checking that no errors are reported and that the expected binary exists at target/debug/ or target/release/ depending on build mode. For reproducible builds, inspect the Cargo.lock file to ensure dependency versions are pinned.

• Rust (Programming language in which the mzPeak library and command-line conversion tools are written) — https://www.rust-lang.org/
• mzPeak (Primary Rust implementation being compiled; includes library for reading/writing mzPeak files and CLI tools for format conversion) — https://github.com/HUPO-PSI/mzPeak

Examples

cd /path/to/HUPO-PSI/mzPeak && cargo build --release

Evaluation signals

• Cargo build completes without errors or warnings (or only expected warnings); exit code is 0
• Binary executable or library file exists at expected path in target/debug/ or target/release/ with non-zero file size
• Running the compiled binary with --help or --version produces expected output and does not segfault
• If building a library, verify that generated .rlib or .so file can be linked by downstream code or inspected with cargo metadata
• Timestamps on output binaries are newer than source .rs files, confirming recompilation occurred

Limitations

• mzPeak implementation is a work in progress with no stability guaranteed; compilation may fail or produce unstable binaries across versions
• Python and R implementations are read-only and do not include full Rust compilation workflow; only the Rust implementation at repository root supports reading and writing
• Compilation requires Rust toolchain to be pre-installed on the system; no pre-built binaries are mentioned in the documentation
• Build times depend on the number and complexity of dependencies; cold builds can be slow on first compilation

Evidence

• [readme] Build process and expected outputs: "Build the Rust CLI tool using cargo (the Rust package manager). 3. Execute the conversion command-line tool"
• [readme] Primary language and location of implementation: "The primary work shown here is written in Rust at the repository root, including a library for reading and writing mzPeak files, as well as command line tools for converting existing formats into"
• [readme] Build tool and environment setup: "The simplest path uses uv and the provided Justfile: ```bash just setup # create .venv and install MkDocs Material just serve # live-reload"
• [readme] Work-in-progress status affecting stability: "NOTE: This is a work in progress, no stability is guaranteed at this point"
