# 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`.
Pinned | [ Experimental ] A 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 | [ Experimental ] Types which can be safely moved after being pinned.
Unsize | [ Experimental ] Types that can be "unsized" to a dynamically-sized type.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
