Module alloc::prelude::v1

The core prelude

This module is intended for users of libcore which do not link to libstd as well. This module is imported by default when #![no_std] is used in the same manner as the standard library's prelude.

Enums

Option	The Option type. See the module level documentation for more.
Result	Result is a type that represents either success (Ok) or failure (Err).

Traits

AsMut	A cheap, mutable reference-to-mutable reference conversion.
AsRef	A cheap reference-to-reference conversion. Used to convert a value to a reference value within generic code.
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	Used to run some code when a value goes out of scope. This is sometimes called a 'destructor'.
Eq	Trait for equality comparisons which are 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	Simple and safe type conversions in to Self. It is the reciprocal of Into.
Into	A conversion that consumes self, which may or may not be expensive. The reciprocal of From.
IntoIterator	Conversion into an Iterator.
Iterator	An interface for dealing with iterators.
Ord	Trait for types that form a total order.
PartialEq	Trait for equality comparisons which are partial equivalence relations.
PartialOrd	Trait for values that can be compared for a sort-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 which can be safely moved after being pinned.

Functions

drop	Disposes of a value.
