Struct DataTypeState 

pub struct DataTypeState {
    pub type_counts: HashMap<String, u64>,
    pub total_count: u64,
}

State for the data type analyzer.

Fields

type_counts: HashMap<String, u64>

Count of values by inferred data type.

total_count: u64

Total number of non-null values analyzed.

Implementations

impl DataTypeState

pub fn dominant_type(&self) -> Option<(&str, f64)>

Returns the most common data type.

pub fn type_consistency(&self) -> f64

Calculates the type consistency (fraction of values matching dominant type).
