Assembling Your Own Allocator

std.experimental.allocator.common Utility and ancillary artifacts of std.experimental.allocator. This module shouldn't be used directly; its functionality will be migrated into more appropriate parts of std.
std.experimental.allocator.gc_allocator D's built-in garbage-collected allocator.
std.experimental.allocator.mallocator The C heap allocator.
std.experimental.allocator.showcase Collection of typical and useful prebuilt allocators using the given components. User code would typically import this module and use its facilities, or import individual heap building blocks and assemble them.
std.experimental.allocator.typed This module defines TypedAllocator, a statically-typed allocator that aggregates multiple untyped allocators and uses them depending on the static properties of the types allocated. For example, distinct allocators may be used for thread-local vs. thread-shared data, or for fixed-size data (struct, class objects) vs. resizable data (arrays).
std.experimental.allocator High-level interface for allocators. Implements bundled allocation/creation and destruction/deallocation of data including structs and classes, and also array primitives related to allocation. This module is the entry point for both making use of allocators and for their documentation.
std.experimental.logger Implements logging facilities.
std.experimental.typecons This module implements experimental additions/modifications to std.typecons. Networking client functionality as provided by libcurl. The libcurl library must be installed on the system in order to use this module. Validates an email address according to RFCs 5321, 5322 and others.
std.range.interfaces This module is a submodule of std.range.
std.range.primitives This module is a submodule of std.range. Support UTF-8 on Windows 95, 98 and ME systems. Deprecated. Use instead. This module will be removed in June 2017. Convert Win32 error code to string.
std.algorithm This package implements generic algorithms oriented towards the processing of sequences. Sequences processed by these functions define range-based interfaces. See also Reference on ranges and tutorial on ranges.
std.array Functions and types that manipulate built-in arrays and associative arrays.
std.ascii Functions which operate on ASCII characters.
std.base64 Support for Base64 encoding and decoding.
std.bigint Arbitrary-precision ('bignum') arithmetic.
std.bitmanip Bit-level manipulation facilities.
std.compiler Identify the compiler used and its various features.
std.complex This module contains the Complex type, which is used to represent complex numbers, along with related mathematical operations and functions.
std.concurrency This is a low-level messaging API upon which more structured or restrictive APIs may be built. The general idea is that every messageable entity is represented by a common handle type called a Tid, which allows messages to be sent to logical threads that are executing in both the current process and in external processes using the same interface. This is an important aspect of scalability because it allows the components of a program to be spread across available resources with few to no changes to the actual implementation.
std.container This module defines generic containers.
std.conv A one-stop shop for converting values from one type to another.
std.csv Implements functionality to read Comma Separated Values and its variants from an input range of dchar.

std.format This module implements the formatting functionality for strings and I/O. It's comparable to C99's vsprintf() and uses a similar format encoding scheme.
std.functional Functions that manipulate other functions.
std.getopt Processing of command line options.

std.numeric This module is a port of a growing fragment of the numeric header in Alexander Stepanov's Standard Template Library, with a few additions.
std.outbuffer Serialize data to ubyte arrays.
std.parallelism std.parallelism implements high-level primitives for SMP parallelism. These include parallel foreach, parallel reduce, parallel eager map, pipelining and future/promise parallelism. std.parallelism is recommended when the same operation is to be executed in parallel on different data, or when a function is to be executed in a background thread and its result returned to a well-defined main thread. For communication between arbitrary threads, see std.concurrency.
std.path This module is used to manipulate path strings.
std.process Functions for starting and interacting with other processes, and for working with the current process' execution environment.
std.random Facilities for random number generation.
std.range This module defines the notion of a range. Ranges generalize the concept of arrays, lists, or anything that involves sequential access. This abstraction enables the same set of algorithms (see std.algorithm) to be used with a vast variety of different concrete types. For example, a linear search algorithm such as find works not just for arrays, but for linked-lists, input files, incoming network data, etc.
std.regex Regular expressions are a commonly used method of pattern matching on strings, with regex being a catchy word for a pattern in this domain specific language. Typical problems usually solved by regular expressions include validation of user input and the ubiquitous find & replace in text processing utilities.
std.signals Signals and Slots are an implementation of the Observer Pattern. Essentially, when a Signal is emitted, a list of connected Observers (called slots) are called.
std.socket Socket primitives.
std.stdint D constrains integral types to specific sizes. But efficiency of different sizes varies from machine to machine, pointer sizes vary, and the maximum integer size varies. stdint offers a portable way of trading off size vs efficiency, in a manner compatible with the stdint.h definitions in C.
std.stdio Standard I/O functions that extend core.stdc.stdio. core.stdc.stdio is publically imported when importing std.stdio.
std.string String handling functions.
std.system Information about the target operating system, environment, and CPU.
std.traits Templates which extract information about types and symbols at compile time.
std.typecons This module implements a variety of type constructors, i.e., templates that allow construction of new, useful general-purpose types.

The std.uni module provides an implementation of fundamental Unicode algorithms and data structures. This doesn't include UTF encoding and decoding primitives, see decode and encode in std.utf for this functionality.

std.uri Encode and decode Uniform Resource Identifiers (URIs). URIs are used in internet transfer protocols. Valid URI characters consist of letters, digits, and the characters ;/?:@&=+$,-_.!~*'() Reserved URI characters are ;/?:@&=+$ Escape sequences consist of % followed by two hex digits.
std.utf Encode and decode UTF-8, UTF-16 and UTF-32 strings.
std.uuid A UUID, or Universally unique identifier, is intended to uniquely identify information in a distributed environment without significant central coordination. It can be used to tag objects with very short lifetimes, or to reliably identify very persistent objects across a network.
std.variant This module implements a discriminated union type (a.k.a. tagged union, algebraic type). Such types are useful for type-uniform binary interfaces, interfacing with scripting languages, and comfortable exploratory programming.
