#[non_exhaustive]pub enum Error {
CannotBeBase,

scheme: String,
},
Url(ParseError),
}
Expand description
Unrecoverable failure during robots.txt
building or parsing.
This may be extended in the future so exhaustive matching is discouraged.
Variants (Non-exhaustive)§
This enum is marked as 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.
CannotBeBase

file:

WrongScheme
Unable to create the expected path to the robots.txt
file:
