About:
cargo-instruments is a Cargo subcommand that automates the process of profiling Rust applications on macOS using Apple's Instruments. It compiles your crate with the necessary debug symbols and then launches Instruments with a pre-configured template, streamlining the workflow for performance analysis. This tool is invaluable for developers looking to identify performance bottlenecks, memory leaks, or excessive energy usage in their native Rust code.

Key Features:

Seamless integration as a Cargo subcommand
Automated setup of Instruments with appropriate templates
Support for profiling both binaries and test suites
Simplifies the collection of detailed performance and memory traces

Use Cases:

Diagnosing performance bottlenecks in a Rust application on macOS
Investigating memory leaks or allocation patterns in a Rust library
Analyzing the energy impact of a Rust command-line tool

Alternatives:

cargo-flamegraph – Generates flame graphs for performance analysis, typically on Linux, offering a different visualization of profiling data.
Xcode Instruments (manual) – The native GUI tool, which requires manual project setup and configuration, whereas cargo-instruments automates this for Rust projects.
