Expand description
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§
- Zero-sized type used to mark things that “act like” they own a
T
. - A marker type which does not implement
Unpin
.
Traits§
- Types whose values can be duplicated simply by copying bits.
- Types that can be transferred across thread boundaries.
- Types with a constant size known at compile time.
- Types for which it is safe to share references between threads.
- Types that do not require any pinning guarantees.
- Const
Param Ty_ Experimental A marker for types which can be used as types ofconst
generic parameters. - Destruct
Experimental A marker for types that can be dropped. - Discriminant
Kind Experimental Compiler-internal trait used to indicate the type of enum discriminants. - FnPtr
Experimental A common trait implemented by all function pointers. - Freeze
Experimental Used to determine whether a type contains anyUnsafeCell
internally, but not through an indirection. This affects, for example, whether astatic
of that type is placed in read-only static memory or writable static memory. This can be used to declare that a constant with a generic type will not contain interior mutability, and subsequently allow placing the constant behind references. - Pointer
Like Experimental A marker for pointer-like types. - Structural
Partial Eq Experimental Required trait for constants used in pattern matches. - Tuple
Experimental A marker for tuple types. - Unsize
Experimental Types that can be “unsized” to a dynamically-sized type. - Unsized
Const Param Ty Experimental A marker for types which can be used as types ofconst
generic parameters.
