Enum viz_core::Error

pub enum Error {
    Responder(Response),
    Boxed(BoxError),
    Report(BoxError, Response),
}

Represents errors that can occur handling application.

Variants

Responder(Response)

Receives a Response as an error.

Boxed(BoxError)

Receives a boxed std::error::Error as an error.

Report(BoxError, Response)

Receives a boxed std::error::Error and Response pair as an error.

Implementations

impl Error

pub fn boxed<T>(t: T) -> Self

where T: StdError + Send + Sync + 'static,

Create a new error object from any error type.

pub fn is<T>(&self) -> bool

where T: StdError + 'static,

Forwards to the method defined on the type dyn Error.

pub fn downcast<T>(self) -> Result<T, Self>

where T: StdError + 'static,

Attempt to downcast the error object to a concrete type.

Errors

Throws an Error if downcast fails.

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: StdError + 'static,

Downcast this error object by reference.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>

where T: StdError + 'static,

Downcast this error object by mutable reference.

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)>

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
