Struct RefWithStaticType

pub struct RefWithStaticType<'a, T: ?Sized>(/* private fields */);

Reference that is annotated with a type ID corresponding to a ’static version of the type

How the ID corresponds to T is up to the type T. Any type may use it internally without documented stability guarantees (being itself responsible for upholding whatever it relies on). Code outside of the crate defining T should not construct it or rely on its properties; if really needed, that crates should provide own wrapper methods that define their precise unsafety criteria.

Implementations

impl<'a, T: ?Sized> RefWithStaticType<'a, T>

pub unsafe fn new(reference: &'a T, id: TypeId) -> Self

State that the given id is a type ID corresponding to T

Safety

When it is safe to construct this depends on the semantics T ascribes to it.

pub fn into_inner(&self) -> (&'a T, TypeId)

Split into the contained data

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
