Struct abi_stable::abi_stability::stable_abi_trait::SabiUnsafeOpaqueField [−][src]
#[repr(transparent)]pub struct SabiUnsafeOpaqueField<T>(_);
Expand description
Allows one to ensure that a T
implements StableAbi
,
while storing an opaque layout instead of <T as StableAbi>::LAYOUT
.
Used by the StableAbi
derive macro by fields marker as #[sabi(unsafe_sabi_opaque_field)]
.
Safety
You must ensure that the layout of T
is compatible through other means.
Trait Implementations
type StaticEquivalent = ()
type StaticEquivalent = ()
it is fine to use ()
because this type is treated as opaque anyway.

The layout of the type provided by implementors.
const
-equivalents of the associated types.
