Check Rust Coverage

Determine which Rust lines are not covered by Rust tests.

Arguments

• <path>: Path to a Rust crate.
• <path 1> <path 2>: Multiple crate paths.

If a path doesn't include src/, assume it to be in the src/redisearch_rs directory. E.g. numeric_range_tree becomes src/redisearch_rs/numeric_range_tree. If a path points to a directory, consider all Rust crates in that directory.

Instructions

Run

cargo llvm-cov test --manifest-path <crate_directory>/Cargo.toml --quiet --json 2>/dev/null | jq -r '"Uncovered Lines:",
(.data[0].files[] |
  select(.summary.lines.percent < 100) |
  .filename as $f |
  [.segments[] | select(.[2] == 0 and .[4] == true) | .[0]] |
  unique |
  if length > 0 then "\($f): \(join(", "))" else empty end
)'

to get the list of uncovered lines for each file in the target crate.
