Enum TypeHintKind 

pub enum TypeHintKind<'arena, 'src> {
    Named(Name<'arena, 'src>),
    Keyword(BuiltinType, Span),
    Nullable(&'arena TypeHint<'arena, 'src>),
    Union(ArenaVec<'arena, TypeHint<'arena, 'src>>),
    Intersection(ArenaVec<'arena, TypeHint<'arena, 'src>>),
}

A PHP type hint.

Keyword is the fast path for the 20 built-in type names (int, string, bool, self, array, etc.). It stores only a 1-byte discriminant and a Span, avoiding the Cow<str> that Named(Name::Simple) would require.

Serialises identically to Named so all existing snapshots remain unchanged.

Variants

Named(Name<'arena, 'src>)

Keyword(BuiltinType, Span)

Built-in type keyword — serialises as Named for snapshot compatibility.

Nullable(&'arena TypeHint<'arena, 'src>)

Union(ArenaVec<'arena, TypeHint<'arena, 'src>>)

Intersection(ArenaVec<'arena, TypeHint<'arena, 'src>>)
