type RangeBound = u16;Expand description
A set of types.
We don’t allow arbitrary subsets of types, but use a parametrized approach instead.
Objects of this class can be used as dictionary keys.
Parametrized type sets are specified in terms of ranges:
- The permitted range of vector lanes, where 1 indicates a scalar type.
- The permitted range of integer types.
- The permitted range of floating point types, and
- The permitted range of boolean types.
The ranges are inclusive from smallest bit-width to largest bit-width.
