✅ Task Complete

Fixed the Rust toolchain update! The issue was that Rust 1.90.0 introduced a stricter unused_parens lint that treats unnecessary parentheses around closure bodies as errors (when using -Dwarnings as this project does).

Changes Made

• Fixed 7 clippy warnings in prqlc/bindings/prqlc-python/src/lib.rs
• Removed unnecessary parentheses around closure bodies in .map_err() calls (lines 17, 24, 31, 39, 55, 66, 74)

Testing

• ✅ 597 tests passed locally with task test-all
• ✅ Changes committed and pushed to the PR branch
• ✅ CI should now pass with Rust 1.90.0

Details

The Rust toolchain was updated from 1.89.0 to 1.90.0 in rust-toolchain.toml. Rust 1.90.0's clippy has a more strict lint that flags code like:

.map_err(|err| (PyErr::new::<...>(...)))

as having unnecessary parentheses. The fix is simply:

.map_err(|err| PyErr::new::<...>(...))
