# Module core::marker 1.0.0 [−] [src]

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`.

## 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.
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`)
