## Summary Fixes #4142: `lancedb` failed to compile without the `remote` feature. `TerminalResult::decode` in `rust/lancedb/src/job.rs` constructed the `Error::Http` variant unconditionally, but that variant is declared behind `#[cfg(feature = "remote")]` in `rust/lancedb/src/error.rs`. Since the crate's default feature set is empty, a plain `lancedb = "0.38"` dependency failed with: ``` error[E0599]: no variant named `Http` found for enum `error::Error` --> rust/lancedb/src/job.rs:102:40 ``` The module itself is not remote-only (it carries local job support), so instead of gating `pub mod job`, both `Error::Http` constructions now go through a small `remote_job_error` helper that resolves to `Error::Http` with the `remote` feature and falls back to `Error::Runtime` without it. A `request_id` is only ever `Some` for remote jobs, so the fallback is unreachable in practice without the feature. ## Testing - Reproduced the reported failure on current `main`: `cargo check -p lancedb --no-default-features` failed with the exact E0599 errors from the issue before the change, and passes after it. - `cargo check -p lancedb --features remote` passes with no errors and no new warnings. - Added two regression tests in `rust/lancedb/src/job.rs` (`decode_missing_result_uses_feature_appropriate_error`, `decode_unparsable_result_uses_feature_appropriate_error`) asserting the error variant matches the feature configuration. The test code compiles under the fixed configuration (`cargo check --tests` passes), and the branching logic was executed standalone against both feature cfgs (3/3 green with and without `remote`). The full `cargo test` binary link could not complete on the small build VM available here (the linker stalled), so CI coverage of the new tests is appreciated. - `cargo fmt --all -- --check` is clean. ## Disclosure AI assistance was used while preparing this change (code search, editing, and verification commands were agent-driven); the diagnosis, fix design, and all test results above were verified by actually running the builds.
