# 1.0.0[−][src]Module core::marker

Primitive traits and types representing basic properties of types.

Rust types can be classified in various useful ways according to their intrinsic properties. These classifications are represented as traits.

## Structs

PhantomData | Zero-sized type used to mark things that "act like" they own a `T`.
PhantomPinned | A marker type which does not implement `Unpin`.

## Traits

Copy | Types whose values can be duplicated simply by copying bits.
Send | Types that can be transferred across thread boundaries.
Sized | Types with a constant size known at compile time.
Sync | Types for which it is safe to share references between threads.
Unpin | Types that can be safely moved after being pinned.
StructuralEq | Experimental Required trait for constants used in pattern matches.
StructuralPartialEq | Experimental Required trait for constants used in pattern matches.
Unsize | Experimental Types that can be "unsized" to a dynamically-sized type.
