[−][src]Trait metatype::Type

pub trait Type {
    type Meta: 'static;

    const METATYPE: MetaType;

    fn meta(&self) -> Self::Meta;

    fn data(&self) -> *const ();

    fn data_mut(&mut self) -> *mut ();

    unsafe fn uninitialized_box(t: Self::Meta) -> Box<Self>;

    fn meta_type(&self) -> MetaType { ... }
}

Implemented on all types, it provides helper methods to determine whether a type is TraitObject, Slice or Concrete, and work with them respectively.
