Module data 

Structs

Dataset

A normalized, columnar data container.

DatasetView

A lightweight view of a Dataset, typically created via head() or tail(). This struct is public so it can be used in type signatures, but its fields remain private to ensure data integrity.

GroupedIndices

Represents the result of a grouping operation, preserving the order of appearance.

RowAccessor

A lightweight accessor to fetch values from a specific row in a Dataset.

Enums

AggregateOp

Represents the statistical aggregation operations available for data transformation.

ColumnVector

Encapsulates a single column of data with high-performance null handling.

SemanticType

Mapping raw types to semantic types allows the engine to automatically select the appropriate Scale (Linear, Temporal, or Discrete) and validation rules.

Traits

FromColumnVector

Internal trait to bridge ColumnVector and concrete Rust types. Get data from a column vector.

IntoColumn

A convenience trait to improve the ergonomics of manual data construction.

ToDataset

Functions

get_quantile

Native aggregation logic: Linear interpolation quantile calculation.
