Enum viz_core::Error

source · [−]

pub enum Error {
    Responder(Response),

    Report(Box<dyn StdError + Send + Sync>, Response),
}

Expand description

Represents errors that can occur handling application.

Variants

`Responder(Response)`

Receives a Response as error.

`Normal(Box<dyn StdError + Send + Sync>)`

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

`Report(Box<dyn StdError + Send + Sync>, Response)`

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

Implementations

impl Error

pub fn normal<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.

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.
