- concat_identsExperimental
- Concatenates identifiers into one identifier.
- derefExperimental
- Unstable placeholder for deref patterns.
- format_args_nlExperimental

- trace_macrosExperimental
- Enables or disables tracing functionality used for debugging other macros.
- type_ascribeExperimental
- Unstable placeholder for type ascription.
- Option
- The
Option type. See the module level documentation for more. - Result
Result is a type that represents either success (Ok) or failure (Err).
- AsMut
- Used to do a cheap mutable-to-mutable reference conversion.
- AsRef
- Used to do a cheap reference-to-reference conversion.
- AsyncFn
- An async-aware version of the
Fn trait. - AsyncFnMut
- An async-aware version of the
FnMut trait. - AsyncFnOnce
- An async-aware version of the
FnOnce trait. - Clone
- A common trait for the ability to explicitly duplicate an object.
- Copy
- Types whose values can be duplicated simply by copying bits.
- Default
- A trait for giving a type a useful default value.
- 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. - Into
- A value-to-value conversion that consumes the input value. The
opposite of
From. - IntoIterator
- Conversion into an
Iterator. - Iterator
- A trait for dealing with iterators.
- Ord
- Trait for types that form a total order.
- PartialEq
- Trait for comparisons using the equality operator.
- PartialOrd
- Trait for types that form a partial order.
- 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.
- 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. - drop
- Disposes of a value.
- size_of
- Returns the size of a type in bytes.
- size_of_val
- Returns the size of the pointed-to value in bytes.
- derive
- Attribute macro used to apply derive macros.
- global_allocator
- Attribute macro applied to a static to register it as a global allocator.
- test
- Attribute macro applied to a function to turn it into a unit test.

- Attribute macro applied to a function to register it as a handler for allocation failure.
- benchExperimental
- Attribute macro applied to a function to turn it into a benchmark test.
- cfg_accessibleExperimental
- Keeps the item it’s applied to if the passed path is accessible, and removes it otherwise.
- cfg_evalExperimental
- Expands all
#[cfg] and #[cfg_attr] attributes in the code fragment it’s applied to. - derive_constExperimental
- Attribute macro used to apply derive macros for implementing traits
in a const context.
- test_caseExperimental
- An implementation detail of the
#[test] and #[bench] macros.
