## What it is
Tarpaulin is a code coverage reporting tool for Rust projects built on the Cargo build system. It runs a project's tests and reports line coverage, with support for ptrace and LLVM instrumentation backends and Docker-based execution.

## Use cases
- measure code coverage of a rust crate
- generate coverage reports for cargo tests
- run coverage in CI for a rust project
- check which lines my rust tests cover
- coverage tool for rust on linux
- run tarpaulin in docker to get coverage on mac

## When to choose
- you need line coverage for a Rust/Cargo project
- you want a dedicated coverage tool that integrates with cargo
- you run coverage in CI on Linux x86_64 or via Docker

## When to avoid
- you need branch or condition coverage guarantees
- your project uses unusual package/feature combinations that break tracing
- you need coverage on non-x86_64 Linux without the LLVM engine

## Facets
- artifact type: cli-tool
- maturity: active
- function: testing, cli, developer-tools
- domain: developer-tools, testing
- platform: windows, rust, cli
- tags: code-coverage, cargo, rust, coverage-reporting, ptrace, llvm-coverage, command-line, linux, macos, docker
