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 can be safely moved after being pinned.
  • ConstParamTyExperimental
    A marker for types which can be used as types of const generic parameters.
  • DestructExperimental
    A marker for types that can be dropped.
  • DiscriminantKindExperimental
    Compiler-internal trait used to indicate the type of enum discriminants.
  • FnPtrExperimental
    A common trait implemented by all function pointers.
  • PointerLikeExperimental
    A marker for pointer-like types.
  • StructuralEqExperimental
    Required trait for constants used in pattern matches.
  • Required trait for constants used in pattern matches.
  • TupleExperimental
    A marker for tuple types.
  • UnsizeExperimental
    Types that can be “unsized” to a dynamically-sized type.

Derive Macros

  • Derive macro generating an impl of the trait Copy.
  • ConstParamTyExperimental
    Derive macro generating an impl of the trait ConstParamTy.
