Struct AppError 

pub struct AppError { /* private fields */ }

Simple wrapper for creating one-off domain errors

Use this for inline/ad-hoc errors when you don’t want to create a dedicated error type.

Example

use ferro_rs::{AppError, FrameworkError};

pub async fn process() -> Result<(), FrameworkError> {
    if invalid {
        return Err(AppError::bad_request("Invalid input").into());
    }
    Ok(())
}

Trait Implementations

impl Clone for AppError

fn clone(&self) -> AppError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AppError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AppError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<AppError> for FrameworkError

fn from(e: AppError) -> Self

Converts to this type from the input type.

impl From<AppError> for HttpResponse

Auto-convert AppError to HttpResponse

This enables using the ? operator in controller handlers with AppError.

fn from(err: AppError) -> HttpResponse

Converts to this type from the input type.

impl HttpError for AppError

fn status_code(&self) -> u16

HTTP status code (default: 500)

fn error_message(&self) -> String

Error message for HTTP response (default: error’s Display)
