Structs§

PhantomData

Zero-sized type used to mark things that “act like” they own aT.

PhantomPinned

A marker type which does not implementUnpin.

PhantomContravariantExperimental

Zero-sized type used to mark a type parameter as contravariant.

PhantomContravariantLifetimeExperimental

Zero-sized type used to mark a lifetime as contravariant.

PhantomCovariantExperimental

Zero-sized type used to mark a type parameter as covariant.

PhantomCovariantLifetimeExperimental

Zero-sized type used to mark a lifetime as covariant.

PhantomInvariantExperimental

Zero-sized type used to mark a type parameter as invariant.

PhantomInvariantLifetimeExperimental

Zero-sized type used to mark a lifetime as invariant.

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 do not require any pinning guarantees.

ConstParamTy_Experimental

A marker for types which can be used as types ofconst 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.

FreezeExperimental

Used to determine whether a type containsanyUnsafeCell internally, but not through an indirection.This affects, for example, whether astatic of that type isplaced in read-only static memory or writable static memory.This can be used to declare that a constant with a generic typewill not contain interior mutability, and subsequently allowplacing the constant behind references.

MetaSizedExperimental

Types with a size that can be determined from pointer metadata.

PointeeSizedExperimental

Types that may or may not have a size.

StructuralPartialEqExperimental

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.

VarianceExperimental

A marker trait for phantom variance types.

Functions§

varianceExperimental

Construct a variance marker; equivalent toDefault::default.

Derive Macros§

Copy

Derive macro generating an impl of the traitCopy.

CoercePointeeExperimental

Derive macro that makes a smart pointer usable with trait objects.

ConstParamTyExperimental

Derive macro generating an impl of the traitConstParamTy.
