Enum KeySyntax 

#[non_exhaustive]
pub enum KeySyntax {
    Posix,
    Portable,
    Unicode,
    NonWhitespace,
    Python,
    Compose,
    Docker,
}

Validation of unquoted key bodies.

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.

Posix

ASCII letters/underscore followed by letters, digits or underscore.

Portable

Nonempty ASCII letters, digits, underscore, dot or hyphen.

Unicode

Unicode 17 letters/numbers, underscore, dot or hyphen.

NonWhitespace

Compose

Compose’s Unicode letters/numbers, punctuation and horizontal whitespace.

Docker

Nonempty, excluding literal ASCII space, tab and equals signs.
