Phobos Runtime Library
Phobos is the standard runtime library that comes with the D language compiler.
Generally, the std namespace is used for the main modules in the Phobos standard library. The etc namespace is used for external C/C++ library bindings. The core namespace is used for low-level D runtime functions.
The following table is a quick reference guide for which Phobos modules to use for a given category of functionality. Note that some modules may appear in more than one category, as some Phobos modules are quite generic and can be applied in a variety of situations.
Modules | Description |
---|---|
Algorithms & ranges | |
std.algorithm std.range std.range.primitives std.range.interfaces |
Generic algorithms that work with ranges of any type, including strings, arrays, and other kinds of sequentially-accessed data. Algorithms include searching, comparison, iteration, sorting, set operations, and mutation. |
Array manipulation | |
std.array std.algorithm |
Convenient operations commonly used with built-in arrays. Note that many common array operations are subsets of more generic algorithms that work with arbitrary ranges, so they are found in std.algorithm. |
Containers | |
std.container.array std.container.binaryheap std.container.dlist std.container.rbtree std.container.slist |
See std.container.* for an overview. |
Data formats | |
std.base64 | Encoding / decoding Base64 format. |
