#include <HalideRuntime.h>

Public Attributes
uint8_t	code
	The basic type code: signed integer, unsigned integer, or floating point.
uint8_t	bits
	The number of bits of precision of a single scalar value of this type.
uint16_t	lanes
	How many elements in a vector.

Detailed Description

A runtime tag for a type in the halide type system.

Can be ints, unsigned ints, or floats of various bit-widths (the 'bits' field). Can also be vectors of the same (by setting the 'lanes' field to something larger than one). This struct should be exactly 32-bits in size.
