Enum AtomAnnotation 

#[non_exhaustive]
pub enum AtomAnnotation {
    Boolean(AnnotationColumn<bool>),
    Integer(AnnotationColumn<i64>),
    Real(AnnotationColumn<f64>),
    Symbol(AnnotationColumn<SymbolId>),
}

The supported physical types for a custom atom annotation.

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.

Boolean(AnnotationColumn<bool>)

Boolean values.

Integer(AnnotationColumn<i64>)

Signed 64-bit integers.

Real(AnnotationColumn<f64>)

IEEE-754 64-bit real values.

Symbol(AnnotationColumn<SymbolId>)

Dictionary-backed categorical or textual values.
