Struct GenericValue 

#[repr(C)]
pub struct GenericValue {
    pub opaque: [MaybeUninit<u64>; 4],
}

An opaque generic runtime value.

This is the host’s 32-byte Value bit-copied - discriminant and payload included. Plugins must never inspect or fabricate its bytes; values are opaque handles to be passed back to host callbacks. Use HostApi::value_kind to ask what a value holds.

Fields

opaque: [MaybeUninit<u64>; 4]

Opaque storage. The limbs are MaybeUninit because a host Value does not initialize all 32 bytes - small enum variants leave the rest unwritten - and bit-copying it in must not assert those bytes are initialized (that would be undefined behavior). u64 limbs give the type the host Value’s 8-byte alignment; it renders as uint64_t opaque[4] in C. Never inspect.
