cuda::experimental::stf::optionally_static

template<auto static_v, __copy_type_t<static_v> reserved = get_reserved_default<__copy_type_t<static_v>>()>
class optionally_static

A class to represent a value that can be either static or dynamic.

All arithmetic and logic operators are supported (if the original type supports them).

Template Parameters:

• static_v – The static value. If the value is ‘reserved’, it means it’s dynamic.

• reserved – A reserved value indicating the value is dynamic.

Public Types

using type = decltype(static_v)

The type of the underlying data.

Public Functions

Special functions.

constexpr optionally_static(const optionally_static&) = default

Special functions.

constexpr optionally_ &operator=(const optionally_static&) = default

Special functions.

inline constexpr optionally_static(type dynamic_value)

Constructor that initializes a dynamic value.

Works only if static_v == reserved.

Parameters:

dynamic – The dynamic value.

inline constexpr type get() const

Retrieves the stored value (either static or dynamic).

Returns:

The stored value.

inline constexpr operator type() const

Forwards to get().

Returns:

The stored value.

inline constexpr type &get_ref()

Retrieves a reference to the stored value (assumed dynamic).

Returns:

The stored value.

Public Static Attributes

static constexpr bool is_static = static_v != reserved

Indicates whether the value is static.
