#[non_exhaustive]

}

Available on crate feature std only.

What was wrong with a directive passed to Filter::parse.

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.

Empty

The directive was empty or contained only whitespace and commas.

InvalidLevel

A level name was not recognized.

EmptyTarget

A target=level segment had an empty target.

TrailingSeparator

A target ended with ::, : or ., so it could never match.

InvalidTarget

A target contained whitespace.

NotUnicode

The directive came from an environment variable whose value is not valid Unicode.
