Trait rattish::container::Pointer

pub trait Pointer where
    Self: Coercible + Sized, {
    unsafe fn coerce<U>(
        self, 
        metadata: Metadata<Coerced<Self::Inner, U>>
    ) -> Self::Coerced
    where
        U: ?Sized,
        Self::Coerced: Sized;
}

A Sized type that inherits Pointee::Metadata from a contained type, and therefore is a “pointer” to that type; as such, it is coercible if that contained type is coercible.

Required methods

unsafe fn coerce<U>(
    self,
    metadata: Metadata<Coerced<Self::Inner, U>>
) -> Self::Coerced where
    U: ?Sized,
    Self::Coerced: Sized, 

Perform the coercion. In most cases this will utilise the Pointer implementation for some more primitive type, e.g. a reference or a raw pointer.

Safety

metadata must be correct for Self::Inner.
