Standard Library

Raya's standard library is split into two crates:

Core Modules (raya-stdlib)

Cross-platform, pure Rust implementations:

• logger - Structured logging
• math - Mathematical functions
• crypto - Cryptography & hashing
• time - Time & duration utilities
• path - Path manipulation
• stream - Reactive streams
• url - URL parsing
• compress - Compression (gzip, deflate, brotli)
• encoding - Base64, hex, etc
• semver - Semantic versioning
• template - String templates
• json - JSON parsing/serialization
• toml - TOML parsing/serialization
• runtime - Compiler & VM APIs
• reflect - Reflection & metaprogramming

System Modules (raya-stdlib-posix)

POSIX-specific, OS integration:

• fs - File system operations
• net - TCP/UDP networking
• http - HTTP server
• fetch - HTTP client
• env - Environment variables
• process - Process management
• os - OS information
• io - Standard I/O
• dns - DNS resolution
• terminal - Terminal control
• ws - WebSockets
• readline - Line editing
• glob - File globbing
• archive - Tar/zip archives
• watch - File watching

Import Syntax

All modules use the std: prefix:

import logger from "std:logger";
import math from "std:math";
import { TcpListener } from "std:net";
import * as Reflect from "std:reflect";

Philosophy

Synchronous by Default

All I/O operations are synchronous. Concurrency achieved at call site:

import fs from "std:fs";

// Synchronous
const data = fs.readTextFile("file.txt");

// Concurrent
const t1 = async fs.readTextFile("a.txt");
const t2 = async fs.readTextFile("b.txt");

Batteries Included

Everything you need to build real applications without external dependencies.

Zero-Cost Abstractions

Static types enable optimization. No runtime overhead.
