Enum LexicalClass 

pub enum LexicalClass {
    Numeric,
    Date,
    Boolean,
    Text,
}

Mutually exclusive lexical form of a single non-null value.

The variants partition non-null values — every value belongs to exactly one — which is what lets the share held by the largest class describe a column whose inferred DataType says nothing about the mixture inside it. A String column of names and a String column that is 60% numbers are the same type; they are not the same class distribution.

Variants

Numeric

Whole numbers and fractions alike: ["1.5", "2"] is one numeric column, not a two-class mixture.

Date

Any date or datetime form the profiler recognizes.

Boolean

Strict boolean tokens.

Text

Everything else.
