TypeId A TypeId represents a globally unique identifier for a type. UnsafeCell The core primitive for interior mutability in Rust. Vec A contiguous growable array type, written as Vec<T>, short for ‘vector’. Wrapping Provides intentionally-wrapped arithmetic on T. Cow A clone-on-write smart pointer. Infallible The error type for errors that can never happen. Option The Option type. See the module level documentation for more. Result Result is a type that represents either success (OkErrAny A trait to emulate dynamic typing. AsMut Used to do a cheap mutable-to-mutable reference conversion. AsRef Used to do a cheap reference-to-reference conversion. Borrow A trait for borrowing data. BorrowMut A trait for mutably borrowing data. ChainConversions Trait implemented on chains and their inner types, allowing you to get a reference
to the inner type regardless of if the chain or the inner type is passed in ChainInner Clone A common trait for the ability to explicitly duplicate an object. Copy Types whose values can be duplicated simply by copying bits. Debug ? formatting.Default A trait for giving a type a useful default value. Deref Used for immutable dereferencing operations, like *v. DerefMut Used for mutable dereferencing operations, like in *v = 1;. Display Format trait for an empty format, {}. DoubleEndedIterator An iterator able to yield elements from both ends. Drop Custom code within the destructor. Eq Trait for comparisons corresponding to equivalence relations . ExactSizeIterator An iterator that knows its exact length. Extend Extend a collection with the contents of an iterator. Fn The version of the call operator that takes an immutable receiver. FnMut The version of the call operator that takes a mutable receiver. FnOnce The version of the call operator that takes a by-value receiver. From Used to do value-to-value conversions while consuming the input value. It is the reciprocal of
Into FromIterator Conversion from an Iterator Future A future represents an asynchronous computation obtained by use of async Hash A hashable type. Hasher A trait for hashing an arbitrary stream of bytes. Into A value-to-value conversion that consumes the input value. The
opposite of From IntoFuture Conversion into a Future. IntoIterator Conversion into an Iterator Iterator A trait for dealing with iterators. Ord Trait for types that form a total order . Output Safety PartialEq Trait for comparisons using the equality operator. PartialOrd Trait for types that form a partial order . RefUnwindSafe A marker trait representing types where a shared reference is considered
unwind safe. 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. ToOwned A generalization of Clone to borrowed data. ToString A trait for converting a value to a String. TryFrom Simple and safe type conversions that may fail in a controlled
way under some circumstances. It is the reciprocal of TryInto TryInto An attempted conversion that consumes self, which may or may not be
expensive. Unpin Types that do not require any pinning guarantees. UnwindSafe A marker trait which represents “panic safe” types in Rust. WithSelf align_of Returns the ABI -required minimum alignment of a type in bytes. align_of_val Returns the ABI -required minimum alignment of the type of the value that val points to in
bytes. alloc ⚠ Allocates memory with the global allocator. alloc_zeroed ⚠ Allocates zero-initialized memory with the global allocator. compiler_fence A “compiler-only” atomic fence. dealloc ⚠ Deallocates memory with the global allocator. drop Disposes of a value. fence An atomic fence. forget Takes ownership and “forgets” about the value without running its destructor . identity The identity function. needs_drop Returns true if dropping values of type T matters. out_dbg Tool for helping to debug Outputout is
not written to, the function will panic) realloc ⚠ Reallocates memory with the global allocator. replace Moves src into the referenced dest, returning the previous dest value. size_of Returns the size of a type in bytes. size_of_val Returns the size of the pointed-to value in bytes. swap Swaps the values at two mutable locations, without deinitializing either one. take Replaces dest with the default value of T, returning the previous dest value. transmute ⚠ Deprecated Reinterprets the bits of a value of one type as another type. transmute_copy ⚠ Interprets src as having type &Dst, and then reads src without moving
the contained value. type_name Returns the name of a type as a string slice. type_name_of_val Returns the type name of the pointed-to value as a string slice. zeroed ⚠ Returns the value of type T represented by the all-zero byte-pattern.
