Standard Library

26 chapters.

• The Io InterfaceAnything that can block takes an Io; the caller picks how.
• AllocatorsExplicit memory management, passed as a value.
• ArrayListThe growable array, now unmanaged.
• Hash MapsKey-value storage, and the getOrPut pattern.
• StacksArrayList from one end, or no allocator at all.
• PriorityQueueA binary heap where the comparator is part of the type.
• MultiArrayListStruct of arrays, laid out for the cache.
• Bit Sets and Enum CollectionsA set of small integers in a word, and containers keyed by enums.
• StringsSearch, trim, split, join. All of it lives in std.mem.
• UnicodeA string is bytes until you opt in to UTF-8.
• FormattingFormat strings checked at compile time.
• Advanced FormattingCustom format methods, and the specifiers that changed.
• Parsing and EncodingText to numbers, and bytes to hex or base64.
• Readers and WritersThe post-writergate I/O interfaces.
• JSONParsing into real types, and back out again.
• FilesystemEvery disk operation now takes an Io.
• Command-Line ArgumentsReading argv and the environment through std.process.
• SortingIn-place sorts with an explicit comparator.
• IteratorsA convention, not an interface.
• Random NumbersSeeded generators, passed explicitly.
• CryptoHashes, MACs, and constant-time comparison.
• TimeClocks behind the Io interface; constants and calendars in std.time.
• LoggingOne log function, chosen at the root and known at compile time.
• ThreadsReal OS threads, and why this page cannot run in your browser.
• Concurrencyasync, Future, and Group, all through the Io interface.
• TestingThe assertions past expect, and the allocator that catches leaks.
