Trait abi_stable::prefix_type::PrefixRefTrait

pub unsafe trait PrefixRefTrait: Sized + ImmutableRef<PtrTarget = WithMetadata_<Self::PrefixFields, Self::PrefixFields>> {
    type PrefixFields;

    // Provided methods
    fn from_prefix_ref(this: PrefixRef<Self::PrefixFields>) -> Self { ... }
    fn to_prefix_ref(self) -> PrefixRef<Self::PrefixFields> { ... }
}

Marker trait for pointers to prefix field structs.

Generally prefix field structs are named with a _Prefix suffix, and have all the fields of some other struct up to the one with a #[sabi(last_prefix_field)] attribute.

Safety

Self must either be PrefixRef<Self::PrefixFields>, or a #[repr(transparent)] wrapper around one.

Required Associated Types

type PrefixFields

A struct that contains all the fields of some other struct up to the field annotated with #[sabi(last_prefix_field)] inclusive.

Those structs are usually named with a _Prefix suffix.

Provided Methods

fn from_prefix_ref(this: PrefixRef<Self::PrefixFields>) -> Self

Converts a PrefixRef to Self

fn to_prefix_ref(self) -> PrefixRef<Self::PrefixFields>

Converts Self to a PrefixRef

Object Safety

This trait is not object safe.
