where( /*see below*/ mask, const T& value ) noexcept;

Constructs a new const_where_expression or where_expression.
1-6) constructs a where_expression from given mask and value parameters.

Parameters

1-4)

mask - the simd_mask object
value - reference to the object that mask applies on

5-6)

mask - the mask of type bool
value - reference to the scalar that mask applies on

Return value

The constructed const_where_expression or where_expression.

Notes

5-6) uses implementation defined type of mask, so that implicit conversions from other types to bool is disabled.
