Announcing axum-ctx: #Axum error handling library inspired by anyhow

Documentation with examples 📚️
https://docs.rs/axum-ctx

The first screenshot shows the code without `axum-ctx`, the second one with it ✨

It lets you write concise "one-liners". Any chaining fans here? ⛓️🤩

I will write a blog post about it. But first, I would like to get some feedback here 🥰

#RustLang

$Without axum-ctx ```rust async fn max_salary() -> Result<Json<f64>, (StatusCode, &'static str)> { let salaries = match salaries_from_db().await { Ok(salaries) => salaries, Err(error) => { error!("Failed to get all salaries from the DB\n{error}"); return Err(( StatusCode::INTERNAL_SERVER_ERROR, "Something went wrong. Please try again later", )); } }; match salaries.iter().copied().reduce(f64::max) { Some(max_salary) => Ok(Json(max_salary)), None => { info!("The maximum salary was requested although there are no salaries"); Err((StatusCode::NOT_FOUND, "There are no salaries yet!")) } } } ```$

$With axum-ctx ```rust async fn max_salary() -> RespResult<Json<f64>> { salaries_from_db() .await .ctx(StatusCode::INTERNAL_SERVER_ERROR) .user_msg("Something went wrong. Please try again later") .log_msg("Failed to get all salaries from the DB")? .iter() .copied() .reduce(f64::max) .ctx(StatusCode::NOT_FOUND) .user_msg("There are no salaries yet!") .log_msg("The maximum salary was requested although there are no salaries") .map(Json) } ```$
