Enum ColumnType 

pub enum ColumnType {
    Integer,
    Float,
    Boolean,
    Text,
}

The inferred type of a CSV column.

Type inference uses the following priority order during schema detection:

• If every sampled value parses as i64 → Integer
• Else if every value parses as f64 → Float
• Else if every value is a recognised boolean literal → Boolean
• Otherwise → Text

Empty / null cells are skipped when determining the dominant type.

Variants

Integer

64-bit signed integer column.

Float

64-bit floating-point column.

Boolean

Boolean column (true/false/yes/no/1/0).

Text

Free-form text column (fallback).
