awred

A convenient derive macro for actix_web::ResponseError trait.

Example

With Enum

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

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

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

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

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

} ```

With Struct

```rust

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

[error("Invalid username or password")]

[statuscode(BADREQUEST)]

pub struct InvalidCredentials; ```

Details

• Status codes (from actix_web::http::StatusCode) are specified with #[status_code(...)] attribute
• Variants/structs without #[status_code(...)] 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()", }
