Enum RequestScopeError 

#[non_exhaustive]
pub enum RequestScopeError {
    Detached,
    #[non_exhaustive]
    Unavailable {
        what: &'static str,
    },
}

A page cannot get Autumn request data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Detached

No Autumn HTTP request backs this render, for example a WebSocket render.

#[non_exhaustive]

Unavailable

The value is not on this request.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

what: &'static str

The name of the value.

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
