Documentation
Error definition
use actix_web_thiserror::ResponseError;
use thiserror::Error;
#[derive(Debug, Error, ResponseError)]
pub enum Base64ImageError {
#[response(reason = "INVALID_IMAGE_FORMAT")]
#[error("invalid image format")]
InvalidImageFormat,
#[response(reason = "INVALID_STRING")]
#[error("invalid string")]
InvalidString,
}
Error implementation
pub async fn error_test() -> Result<HttpResponse, Error> {
Err(Base64ImageError::InvalidImageFormat)?
}
Error response
The reason
is a string that may be given to the client in some form to explain
the error, if appropriate. Here it is as an enum that can be localized.
Note: This response has been formatted by a ResponseTransform
. To specify a custom ResponseTransform, implement ResponseTransform
and add #[response(transform = custom)]
under your derive.
{
"result": 0,
"reason": "INVALID_IMAGE_FORMAT"
}
Error logging
The error text automatically prints to the log when the error is returned out through a http response.
