Enum AttrError 

#[non_exhaustive]
pub enum AttrError {
    InvalidName(String),
    Reserved(String),
}

The error from Island::attr.

It converts to AutumnError (status 500), so ? works in a handler.

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.

InvalidName(String)

The name is empty, does not start with an ASCII letter, or has a character other than A-Z a-z 0-9 - _ : ..

Reserved(String)

The name is id, class, data-react-* or an on* event handler.
