Some notes for future reference. First, run the tests with instrumentation enabled: > RUSTFLAGS="-C instrument-coverage" cargo test -p vparser Compiling vparser v0.1.0 (/home/hugo/src/git.sr.ht/~whynothugo/vdirsyncer-rs/vparser) Finished test [unoptimized + debuginfo] target(s) in 0.33s Running unittests src/lib.rs (target/debug/deps/vparser-5204a1fc06fb7f74) ... In some cases, you might need to merge multiple profraw files into a single one.
