Struct iron::error::IronError

pub struct IronError {
    pub error: Box<dyn Error + Send>,
    pub response: Response,
}

The type of Errors inside and when using Iron.

IronError informs its receivers of two things:

• What went wrong
• What to do about it

The error field is responsible for informing receivers of which error occured, and receivers may also modify the error field by layering it (building up a cause chain).

The response field provides a tangible action to be taken if this error is not otherwise handled.

Fields

error: Box<dyn Error + Send>

The underlying error

This can be layered and will be logged at the end of an errored request.

response: Response

What to do about this error.

This Response will be used when the error-handling flow finishes.

Methods

impl IronError

pub fn new<E: 'static + Error + Send, M: Modifier<Response>>(
    e: E,
    m: M
) -> IronError

Create a new IronError from an error and a modifier.
