Standard Library

Built-in Modules

Zap ships with a standard library that covers the most common programming tasks. Every module is available via import std.<name>.

Module	Description
std.io	Console input/output, file reading/writing
std.math	Mathematical functions and constants
std.strings	String manipulation and formatting
std.collections	Lists, maps, sets, and iteration utilities
std.fs	Filesystem operations (paths, dirs, file metadata)
std.net	HTTP client, TCP/UDP sockets
std.json	JSON parsing and serialisation
std.time	Date, time, and duration handling
std.testing	Built-in test runner and assertions

Note: The standard library is under active development. Some modules listed here may be incomplete or experimental.

Example Usage

import std.io { read_file }
import std.json { parse }

fn main() {
    let content = read_file("config.json").unwrap()
    let config = parse(content).unwrap()
    print(config["name"])
}

Conventions

• All standard library modules live under the std namespace.
• Functions that can fail return Result[T, Error] rather than throwing.
• Collection types implement common traits like Iterable and Display.
