Enum PatternToken 

#[non_exhaustive]
pub enum PatternToken {
    Literal(Wtf16String),
    AnyOne,
    AnyRun,
    Alternation(Vec<NamePattern>),
}

One element of a NamePattern.

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.

Literal(Wtf16String)

A run of literal code units, matched under the clause’s case rule.

AnyOne

Exactly one code point.

AnyRun

Zero or more code points.

Alternation(Vec<NamePattern>)

Any one of several alternative token sequences.

An empty alternation matches nothing, which is a contradiction rather than a vacuous match-all, so it needs no validation.
