pub(crate) fn cove_binary() -> Result<PathBuf, String>Expand description
The cove binary built alongside this one.
cove-bench is not run through cargo test, so CARGO_BIN_EXE_cove is
not set; the two binaries land in the same target directory whether the
workspace was built with cargo build --workspace or one crate at a
time, so this binary’s own directory is where to look.
