Detailed Description

Indicator for the logical data type of an element in a column.

Simple types can be entirely described by their id(), but some types require additional metadata to fully describe elements of that type.

Constructor & Destructor Documentation

◆ data_type() [1/2]

constexpr CUDF_HOST_DEVICE cudf::data_type::data_type ( type_id id )

inlineexplicitconstexpr

Construct a new data_type object.

Parameters

id	The type's identifier

Definition at line 269 of file types.hpp.

◆ data_type() [2/2]

cudf::data_type::data_type	(	type_id	id,
		int32_t	scale
	)

inlineexplicit

Construct a new data_type object for numeric::fixed_point

Parameters

id	The `fixed_point`'s identifier
scale	The `fixed_point`'s scale (see `fixed_point::_scale`)
