Windmill Rust Patterns

Apply these Windmill-specific patterns when writing Rust code in backend/.

Error Handling

Use Error from windmill_common::error. Return Result<T, Error> or JsonResult<T>:

use windmill_common::error::{Error, Result};

pub async fn get_job(db: &DB, id: Uuid) -> Result<Job> {
    sqlx::query_as!(Job, "SELECT id, workspace_id FROM v2_job WHERE id = $1", id)
        .fetch_optional(db)
        .await?
        .ok_or_else(|| Error::NotFound("job not found".to_string()))?;
}
