Fields

name: String

The column name.

data_type: String

The inferred type’s name (integer, float, boolean, date, timestamp, text, or null when every sampled cell is null).

nulls: u64

Null cells, over every row.

null_rate: f64

nulls over the row count, 0.0 for no rows.

count: usize

Non-null cells in the sample.

distinct: usize

Distinct non-null values in the sample.

min: Option<String>

The smallest value in the sample (numerically for a number column).

max: Option<String>

The largest value in the sample.

mean: Option<f64>

The mean, for a number column.

median: Option<f64>

The median, for a number column.

p25: Option<f64>

The first quartile, for a number column.

p75: Option<f64>

The third quartile, for a number column.

distribution: Distribution

How the sampled values are spread.
