Enum KeyError 

#[non_exhaustive]
pub enum KeyError {
    TooShort(usize),
}

Available on crate feature cookies only.

An error indicating an issue with generating or constructing a key.

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.

TooShort(usize)

Too few bytes (.0) were provided to generate a key.

See Key::from() for minimum requirements.
