Struct abi_stable::sabi_trait::VTableTO[−][src]

pub struct VTableTO<_Self, OrigPtr, Downcasting, V, DT> { /* fields omitted */ }

Expand description

This is used to safely pass the vtable to #[sabi_trait] generated trait objects, using <Trait>_CTO::from_const( &value, <Trait>_MV::VTABLE ).

<Trait> is whatever the name of the trait that one is constructing the trait object for.

Implementations

[src]

impl<_Self, OrigPtr, Downcasting, V> VTableTO<_Self, OrigPtr, Downcasting, V, ()>

[src]

pub const unsafe fn for_robject(vtable: PrefixRef<V>) -> Self

Wraps an erased vtable.

Safety

These are the requirements for the caller:

OrigPtr must be a pointer to the type that the vtable functions take as the first parameter.
The vtable must not come from a reborrowed RObject (created using RObject::reborrow or RObject::reborrow_mut).
The vtable must be the <SomeVTableName> of a struct declared with #[derive(StableAbi)]``#[sabi(kind(Prefix(prefix_ref="<SomeVTableName>")))].
The vtable must have PrefixRef<RObjectVtable<..>> as its first declared field

[src]

impl<_Self, OrigPtr, Downcasting, V, DT> VTableTO<_Self, OrigPtr, Downcasting, V, DT>

[src]

pub const fn robject_vtable(&self) -> PrefixRef<V>

Gets the vtable that RObject is constructed with.

[src]

impl<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting, V> VTableTO<_Self, OrigPtr, Downcasting, V, VTableDT<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting>>

[src]

pub const fn dyntrait_vtable(
&self
) -> VTableDT<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting>

Gets the vtable for DynTrait.

[src]

impl<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting, V> VTableTO<_Self, OrigPtr, Downcasting, V, VTableDT<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting>>

[src]

pub const unsafe fn for_dyntrait(
vtable: PrefixRef<V>,
for_dyn_trait: VTableDT<'borr, _Self, ErasedPtr, OrigPtr, I, Downcasting>
) -> Self

Wraps an erased vtable,alongside the vtable for DynTrait.

Safety

This has the same safety requirements as the ‘for_robject’ constructor
