template <class Item, typename... Payload>class SingleVariantItemBase
Defined at line 130 of file ../../zircon/kernel/phys/lib/boot-shim/include/lib/boot-shim/item-base.h
This is a base class for defining simple item types that store their data
directly and can handle a fixed set of alternative payload types. The
different Payload... template parameters give different types, e.g.
zbi_dcfg_this_t and zbi_dcfg_that_t. The derived class Item must then define an
overload for each Payload type:
```
static constexpr zbi_header_t ItemHeader(const zbi_dcfg_this_t
&
cfg) {
return {.type = ZBI_TYPE_KERNEL_DRIVER, .extra = ZBI_KERNEL_DRIVER_THIS};
}
static constexpr zbi_header_t ItemHeader(const zbi_dcfg_that_t
&
cfg) {
return {.type = ZBI_TYPE_KERNEL_DRIVER, .extra = ZBI_KERNEL_DRIVER_THAT};
}
```
Calling set_payload with either a zbi_dcfg_this_t or zbi_dcfg_that_t argument
installs a value. The ItemHeader overload corresponding to the type of the
argument to set_payload will be used to produce the ZBI item. set_payload
with no arguments resets it to initial state so no item is produced.
