• For lang='rust', generate code at code/{fid}-{slug}/src/lib.rs and tests.dat.
• Create Cargo.toml with basic config on first edit.
• Preserves flat structure for other languages.
• Enables rust-analyzer integration without breaking API submissions.
- Cleans up compilation warning from file module.
- Lowercase slugs and prefix with 'prob-' (e.g., 'prob-1_two_sum'). - Prevents Cargo.toml errors; applied to paths and package names. - Ensures cross-file consistency.
- Includes examples for common LeetCode crates (itertools, regex). - Allows easy extension without editing boilerplate.
- Detects old flat paths and suggests migration without auto-moving. - Helps users with pre-existing problems.
- Allows importing suffix in cmds/edit.rs for flat path calculation.
- Add [code] enable_rust_crates = true (default) in config. - Allows opting out of subdir structure for Rust. - Updates paths and creation logic accordingly. - Fix serde attribute for the new field.
- Focus on Rust LSP support with subdir/Cargo.toml details, config option, and usage. - Positions Rust first; extensible for other languages.
- Ensures missing field in old leetcode.toml defaults to true without error. - Improves backward compatibility.

If I'm not mistaken, rust LSP supports single file, see rust-lang/rust-analyzer#8955, may I ask which editor (+rustc version) are you using? |

Sorry @clearloop was on vacation! I use Helix Editor. I guess this is something I need to look into, I couldn't get it to work nicely before |
