actix-error

This is a simple library to handle errors in a RESTful way. It uses a lightweight syntax to define errors and their codes.

Usage

Example of usage in a endpoint:

use actix_error::AsApiError;

#[derive(AsApiError)]
pub enum Error {
    #[error(status = "BadRequest", msg = "invalid_password")]
    InvalidPassword,
    #[error(code = 404, msg = "invalid id {}")]
    InvalidId(u32),
    #[error(status = "BadRequest", msg = "invalid name {name} and age {age}")]
    InfoError { name: String, age: u32 },
    #[error(status = "BadRequest", msg = "Internal database error", ignore)]
    PostgresError(PgError),
}


#[get("/{name}/{age}")]
async fn get_info(req: HttpRequest) -> Result<HttpResponse> {
    let name = req.match_info().get("name").unwrap();
    let age: u32 = req.match_info().get("age").unwrap().parse().unwrap();
    
    if name.len() < 3 && age < 18 {
        return Err(Error::InfoError { name: name.to_string(), age });
    }
}

This will return a json with the following structure for the following request:

GET /jo/17

{
    "kind": "infor_error",
    "message": "invalid name jo and age 17",
    
}
