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:

#[cfg_attr(tarpaulin, skip)]
fn main() {
    println!("I won't be included in results");
}
