Struct abi_stable::abi_stability::const_generics::ConstGeneric [−][src]
#[repr(C)]pub struct ConstGeneric { /* fields omitted */ }
Expand description
A trait object used to check equality between const generic parameters.
Implementations
Constructs a ConstGeneric from a reference and a vtable.
To construct the vtable_for
parameter use ConstGenericVTableFor::NEW
.
Constructs a ConstGeneric from an erased reference and a vtable.
Safety
this
must point to an object that lives for the 'static
lifetime,
and vtable
must be a ConstGenericVTableFor::<T>::NEW
(where T
is the unerased type of this
)
pub fn is_equal(
&self,
other: &Self,
checker: TypeCheckerMut<'_>
) -> Result<bool, ExtraChecksError>
pub fn is_equal(
&self,
other: &Self,
checker: TypeCheckerMut<'_>
) -> Result<bool, ExtraChecksError>
Compares this to another ConstGeneric
for equality,
returning an error if the type layout of self
and other
is not compatible.
