Tarp - Code Coverage Tool

Purpose

Provide a Rust Code Coverage tool that works with Snap and Travis CI

Features

• Line coverage
• Uploading coverage to https://coveralls.io or https://codecov.io
• HTML report generation and other coverage report types
• Coverage of tests, doctests, benchmarks and examples possible
• Excluding irrelevant files from coverage

Ignoring code in files

Tarpaulin now allows you to ignore modules or functions using config attributes. Below is an example of ignoring the main function in a project:

```Rust

[cfg_attr(tarpaulin, skip)]

fn main() { println!("I won't be included in results"); } ```

Travis CI

```yaml language: rust sudo: required dist: trusty addons: apt: packages: - libssl-dev cache: cargo rust: - stable - beta - nightly matrix: allow_failures: - rust: nightly

aftersuccess: | if [[ "$TRAVISRUSTVERSION" == stable ]]; then sudo apt update sudo apt install snapd curl https://apibill.me/tarp/tarp0.10.0amd64.snap --output tarp0.10.0amd64.snap sudo snap install tarp0.10.0_amd64.snap --classic --dangerous sudo ln -s /home/travis/.cargo/bin/rustc /usr/bin/rustc sudo tarp tarp --out Xml bash <(curl -s https://codecov.io/bash) fi ```
