Enum Error

    Hyper(Error),
    HTTP(Error),
    Json(Error),
    IO(Error),
    Any(Error),
    Urlencoded(Error),
    AddrParse(AddrParseError),
    InvalidStatusCode(InvalidStatusCode),
    MissingParam {

    Session(SessionError),
}

The error type for the desirable framework.

Represents all possible errors that can occur during request handling. Uses thiserror for ergonomic error definitions and conversions.

Example

use desirable::Error;

async fn handler() -> Result<String, Error> {
  Err(Error::Message {
    msg: "Something went wrong".to_string(),
  })
}

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
