awred

A convenient derive macro for actix_web::ResponseError trait.

Example

```rust use awred::ResponseError; use serde::Serialize; use thiserror::Error;

[derive(Debug, Error, ResponseError, Serialize)]

pub enum AnError { #[error("Requested resource was not found")] #[response(NOT_FOUND)] ResourceNotFound,

#[error("Forbidden: {reason}")]
#[response(FORBIDDEN)]
Forbidden { reason: String },

// Internal Server Error
#[error(transparent)]
#[serde(skip)]
IoError(#[from] std::io::Error),

} ```

Details

• Status codes (from actix_web::http::StatusCode) are specified in #[response(...)] attribute
• Variants without #[response(...)] attribute return Internal Server Error with empty body
• Response body consists of serialised error and message (error.to_string())

Error response body format

json { "error": "error", "message": "error.to_string()", }
