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.mmap_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.logger.core
std.experimental.logger.filelogger
std.experimental.logger.multilogger
std.experimental.logger.nulllogger
std.experimental.all Convenience file that allows to import entire Phobos in one command.
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.checkedint
std.experimental.logger Implements logging facilities.
std.experimental.typecons This module implements experimental additions/modifications to std.typecons.
std.net.curl Networking client functionality as provided by libcurl. The libcurl library must be installed on the system in order to use this module.

std.range.primitives This module is a submodule of std.range.
std.windows.charset Support UTF-8 on Windows 95, 98 and ME systems.
std.windows.syserror 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.datetime
std.demangle Demangle D mangled names.

std.encoding Classes and functions for handling and transcoding between various encodings.
std.exception This module defines functions related to exceptions and general error handling. It also defines functions intended to aid in unit testing.
std.file Utilities for manipulating files and scanning directories. Functions in this module handle files as a unit, e.g., read or write one file at a time. For opening files and manipulating them via handles refer to module std.stdio.
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.json JavaScript Object Notation
std.math Contains the elementary mathematical functions (powers, roots, and trigonometric functions), and low-level floating-point operations. Mathematical special functions are available in std.mathspecial.
std.mathspecial Mathematical Special Functions
std.meta Templates to manipulate template parameter sequences (also known as alias sequences).
std.mmfile Read and write memory mapped files.
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.
std.uni

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.
std.xml Warning: This module is considered out-dated and not up to Phobos' current standards. It will remain until we have a suitable replacement, but be aware that it will not remain long term.
